History Fridge / DeadSpace2

* The most prominent case of Fridge Horror for this troper was looking at his own weapons. The sniper rifle that fires explosive warheads, obviously intended to cause horrific mutilation and likely death, at first assumed to be a military weapon, is in fact a ''riot control measure''. That's right, Titan's idea of controlling disorderly gatherings is to fire ''high caliber explosive rounds'' into them.

* Retroactively made even more horrific in the sequel [[spoiler: where Unitologist fanatics managed to beat EarthGov soldiers and police forces, executing innocent people en masse. It's not just horrifying that such a weapon would be considered riot control, but as it turns out ''it wasn't brutal enough''.]]

* [[spoiler: The only thing worse than watching Issac stick a needle in his own eye is realizing that the machine actually has the capability and controls for self eye-probing.]]
* When you use a giant drill machine to [[spoiler: get into Earthgov sector, you are smashing a big hole in the only thing that's seperating the necromorphs and everyone else. Including all of the evacuated civilians.]]

* So Ishimura again huh? And again you have to fix that damn generator. Wait what the hell is that noise? Banging Inside the wall? Oh well no one is crawling out anyway... Yeah i remember that the last time i was there, there was that weird growth on the wall. All that dead tissue and what not. Hold on, is that Necromorph who revived itself inside, or a poor human who slipped and fell down some crevice?

* Why is it that Isaac, an engineer who has never had any real military training or equipment, been able to do so well against the Necromorphs while the Security and Military Forces have been brutally slaughtered? Simple, it's because Isaac is an Engineer. How do Necromorphs attack their victims? By cutting them into pieces, burning their flesh off, and just plain blowing them up, which are all the kinds of danger an engineer would face in his job, albeit not in this particular fashion. The engineers would have suits specifically designed to be resistant to cuts, burns, and small explosions, which could all happen with the loadout for engineers being things like Detonators and Line Guns. And seeing as all of an engineer's loadout are geared towards cutting and exploding (the pulse rifle could be an exception to this, but maybe it's the engineer variant of it), they are the perfect weapons to take on the necromorphs, who only die from having their limbs cut off or being blown up. The Military and Security Forces all have suits and weapons that are meant to fight humans with human weapons, like the pulse rifle. They aren't really built to combat cutting attacks because, really, who would come after someone in a full military grade suit wielding a pulse rifle with just a knife? Unless there is some kind of future Spec OPs we don't know about who can pull that off, but they certainly aren't on the Sprawl. This would also explain when [[spoiler: Isaac gets attacked by the Security Force late in the game he takes so much damage from them. His suit is designed to resist attacks from something like a Plamsa Cutter or something similar, but it certainly wouldn't hold up to a pulse rifle.]]

** Then add in what Nicole hallucination says near the end, [[spoiler:that convergence requires one last body, that of the maker of the marker to be added to it.]] So not only was he tortured and kept suspended like that for years, ultimately he was to become the [[spoiler:catalyst for making whatever the heck the markers are trying to create.]]
*** Were you reffering that they actually burned in the end, as Convergence started? Because you can see them engulfed in flames.

** Daina also yells that her "brother" died to get Isaac out of that hospital. Franco's black and Daina's white; the possibility of adoption aside, this is [[spoiler: most likely yet another slip on her part. He's her "brother" in the sense that he belongs to the same order as her.]]
*** That would explain his weird hands, when you kill him several times through the game. Ewww...

** This is further supported in Dead Space 1 where a rare type of slasher necromorphs, have legs covered in the remains of armored suits, resembling Isaac's own suit. Because of said armor shooting them in the legs does not work, indicating that armored mining suits are indeed resistant to damage from mining tools.

** This also makes Tiedemann the equivalent of the Pharisees and/or Romans. He even impales Isaac through the hand, after repeatedly trying to stop him in less direct fashion.

** The Black Marker (Pre-Game), the original, works as intended - It contains the virus and influences the minds of those around it to keep them from meddling. The Red Marker (VideoGame/DeadSpace), its copy, is defective - It still attempts to ward off humans, but does a much poorer job. In addition, it can barely contain the virus. The Golden Marker (VideoGame/DeadSpace2) is a copy of a copy, and it's completely broken - it actively attempts to spread the infection.
*** [[spoiler: {{Jossed}} in the [[VideoGame/DeadSpace3 sequel]], seemingly ''all'' Markers [[ThePlan have a agenda to revive the]] [[ThatsNoMoon Brethren Moon]] that'd been locked in hibernation above Tau Volantis by the [[AbsentAliens extinct alien race]] or create a whole new Brethren Moon altogether. That said however, it might of been very well possible that the Red Marker in the original might have been possibly been a faulty copy that wanted to do the opposite of it's intended purpose and put the Necromorph outbreak to a sudden halt, though it could be just as likely that it simply wanted to start it's own Convergence Event with the fresh amount of bodies available to it after the massacre that devastated both Aegis VII and the Ishimura by [[ImpersonationGambit manipulating Isaac by projecting Nicole]].]]
*** [[spoiler: That or that the Red Marker never absorbed it's creator which was necessary to finish the Convergence and thus it wanted to stay dormant. The Golden Marker failed in it's task to absorb the creators, but the one that created the Brethren Moon must have succeed centuries ago.]]
*** [[spoiler: Or maybe it just needed to be in the proper spot for Convergence to take place--right next to the nascent Hive Mind.]]

** [[spoiler: And that's exactly what seems to be happening in the last few moments of Awakening.]]

** Might be some FridgeBrilliance here: there's guards standing about 24/7 with these things, each wearing bullet-proof and face-concealing armor... so nobody is allowed near anything that might be used as a weapon. Something that might help fight off Necromorphs. This is why the station is taken over so quickly! Nobody had anything with which to defend themselves!
** Similarly, FridgeBrilliance suggests this could be a case of DeliberateValuesDissonance. To us living on Earth, the idea of killing rioters outright is horrific and draconian... but think about how much property damage and destruction a riot can cause, and remember that a self-contained environment like a spacestation is a ''horrifyingly'' fragile one. If a riot gets out of hand, it could kill everyone aboard the station by damaging the vital systems that keep air and warmth in and the killing vacuum of space out. So, it's logical -- if ruthless -- to quickly terrorise rioters into submission by killing ringleaders quickly and messily before things can get that bad.
** Retroactively made even more horrific in the sequel [[spoiler: where Unitologist fanatics managed to beat EarthGov soldiers and police forces, executing innocent people en masse. It's not just horrifying that such a weapon would be considered riot control, but as it turns out ''it wasn't brutal enough''.]]

** [[spoiler: Are we sure that's where the civilians were being evacuated to? Since Tiedemann sincerely was interested in their safety, wouldn't it have been easier to send them to some other station rather than gather them into what is not only a classified project, but the project that caused the disaster?]]
* The Unitologists were killing themselves before the Marker was there. That means hundreds of people committed suicide and Titan Station did nothing to stop it.
** Following that same train of thought, Unitology encourages ''suicide''. And perhaps the worst realization: Unitology is not just an accepted religion, it is an accepted religion with power on par with Earthgov. They can do whatever they want because ''no one can stop them''.

** To add to this, modern body armor is bullet proof. It is also very easily penetrated by a knife which it is not designed to handle.

-it is scary once you realise you control the eye machine and you have seen the death scene.so that means inuniverse isaac gets into a machine that can malfunction and kill him

[[AC:FridgeHorror]]
* ''DeadSpace2''. In a game series known for it's attempts at gross out horror, some of the most unsettling parts come from the actual setting of the game.
** Unitology? Every person that has died in the last ''two hundred years'' is stored somewhere in deep space, inevitable fuel just sitting there to aid the Necromorphs in expanding across the stars. Their religion is also bigger than any of the religions we know of today. At the drop of a hat, there could be ''billions'' of Necromorphs descending upon Earth, and no one could stop it.

[[folder: FridgeLogic:]]

When you finally reach Daina, [[spoiler: two Unitologist goons grab Isaac by the arms making him unable to move anymore and resist them taking him to their shuttle. Which would make sense if he was still in his patient RIG and unarmed. However Isaac is armed with at least a Plasma Cutter and possibly several other weapons and wears an armored RIG capable of withstanding attacks by Necromorphs. Not to forget having just fought himself through countless of these monsters. The two goons are unarmed and dressed in robes. The hell?]].
** Isaac has no problem killing necromorphs and based on the early part of the game does genuinely care about other people. He tries to save the patient stuck on the operating table, and seems genuinely upset with what happens to the guys in the beginning. Not to mention they are unarmed, the back story for him from the two games is that he was raised well by his parents thus having great determination and a moral compass. If they were armed and trying to harm him, he probably would have retaliated.
*** He still had no problem kicking the last goon away into certain death. Though then again unlike the patient he really would have no way of saving him anyway.
*** The thugs hid on either side of the door and ambushed him while Daina distracted him, and he wasn't expecting an attack. He thought Daina was going to help him. Isaac is badass but he's not psychic. How exactly is Isaac supposed to use that plasma cutter on them with his arms restrained? His armored rig is tough but it doesn't boost his physical strength. Also, are you sure the thugs were unarmed? At the least they had stasis modules and presumably would have used them if Isaac had put up more of a fight, and I have a hard time believing they could have stayed alive that long on a necromorph infected ship without weapons.
**** He still wears armored boots and could either have stomped or shot on the feet of one and punched the other to get free.
*** We don't even know if they would have actualy succeded in holding him in place. If the gunship wouldn't have turned up Isaac could have just aswell freed himself with either his armored boots, his weapon or stasis module, without killing them. He most likely was just still shocked over the turn of events or wanted to still try to reason with them.
**** I got this impression too. He didn't seem to be fighting them very hard, I think he was waiting until after he'd pumped Daina for as much information as he could get to really start struggling but the gunship showed up and made that unnecessary.

In an age so advanced, why doesn't Isaac use night vision?
* Preservation of tension. The weapon lights and light from the helmet only illuminate a small area, night vision would also ruin the moments where the lights go out.

[[WMG: Government Sector security.]]
Can someone explain this to me? The Goverment Sector compound has a ridiculously reinforced main door. Yet all it takes is removing one power cell and the door may as well be made out of cardboard. WHO THE HELL DESIGNED THIS PLACE? I mean, seriously? What was the plan for if the power cell went bad, which happens with alarming frequency throughout the game. I know there's a back up power system but why isn't something like that automatically brought online in the case of a power outage? I mean if you're going to be this sloppy in designing your impenetrable fortress where your planning on waiting out the Necromorph outbreak, you deserve to be eaten. One last thing, if your defenses are reliant on a single power cell, why aren't you guarding that power cell in case, oh I don't know, some CEC Engineer on the run from your troops decides to disable your defenses so as to let the Necromorphs distract you from stopping him from destroying your precious Marker.
* The clear implication from later on in the Government Sector is that the necromorphs were already tunneling through the walls and spreading through the rock. It seems to have just been a matter of time
** Is that the case? I mean yeah it would've happened eventually but it would've taken ages what with all the routes into Government sector cut off. Issac and Ellie at the very least severely reduced that time by drilling their way to the compound. And there isn't a single hint of a Necromorph inside the base prior to Issac yanking the power cell. Besides the Necromorphs charge head on through the front door, which is not typical behavior, which suggest there were no other routes at least until they reached an air vent which was likely behind the wall of soldiers Issac needed to get past.
* Yeah, I thought the single unprotected power cell required to open the security door was really lame too. They could have at least thrown in a hack minigame to release the cover and made you pull out 2 or 3 power cells, would have made it a bit more believable. Also, how exactly does turning off the power open the door?
** When you remove the power cell, you can hear some of the soldiers say something about the "kinetic restraints" holding the door closed. There was probably a whole horde of necromorphs banging on the door after Isaac got through, and once the power cell was removed, they just forced the door open through weight of numbers and charged through.
*** Considering that roughly 30 necromorphs plus the Ubermorph enter within seconds of power being lost, this seems the obvious answer.
* It's quite possible that the power cell WAS the back up security power, or even the back up to the back up. After all, the colony got it's power cut off, large chunks got sliced up by a solar beam, the whole thing was dragged by a gravity tether and more damage was done via a gigantic drill rig. Redundant systems can only take so much punishment. I'm surprised the building was standing at all.
** One of the soldiers says "we just lost auxiliary power!" when Isaac pulls the power cell, so it's not just a possibility, that really was the backup power source. Now why the backup power source was so poorly protected, that's another question entirely.
* Take note of the fact that in order to get access to the internal portion of Government sector, Isaac used his engineering mojo on some of the equipment near the door. Chances are, Isaac broke something when he opened the door, and the power outage triggered a malfunction in the door's locking mechanism. Isaac himself probably damaged the systems that would have prevented that.
[[WMG: Government Sector Gunship]]
Why is there a fully fuelled, armed and functional gunship docked near the entrance to the Government Sector, unlocked and ready for the taking by anyone that knows how to pilot it? Why didn't Tiedemann have his men hunting down Isaac in it, or at least move it somewhere where Isaac couldn't find it and use it to bypass literally all of his defenses? Seriously, if Isaac wasn't overcome with guilt and a HeroComplex he could have flown that gunship directly to the marker, just as Ellie does at the end of the game.
* This is just a guess but at that point all of the soldiers that would have been protecting the facility were either busy being eaten by Necromorphs or dead. So, Issac may have been unable to use the gunship to go straight to the Marker as the soldiers would have shot him down for trying it. After he distracted them with a massive Necromorph attack might have been a different story. So, there may have been no "need" to move it somewhere safer. Also, Tiedeman had initiated Operation Endgame which appears to amount to "Return to Base and wait it out in our impenetrable Fortress complex". To be fair, this is a perfectly sensible plan as it seems to have been working up until the point Issac cut the power and let the Necromorphs have at it. The plan to deal with Issac seemed to be cut off all his routes of escape and let the Necromorphs deal with him. It would've worked if Issac weren't an Engineer, which might as well be a superpower by this point as it literally makes him the strongest fighter in the entire game with enough smarts to out-maneuver Tiedeman's attempts to kill him.
[[WMG: Environmental Damage]]
* As in the first game, there is the question of why Isaac's [weaponized] tools do no significant damage to the game's indoor environments. In supplementary material, we are repeatedly told how such devices as the Line Gun are designed to cut cleanly through large chunks of solid rock. Yet, when a shot rips through a necromorph (or misses the target entirely) and strikes the wall behind it, no real damage is visible--this, in spite of the fact that javelins and necro claws DO stick in the walls. Consider also the Contact Beam, whose alt-fire mode is a kind of energy jackhammer for softening up sections of planetoid. Oddly, it does nothing to the floor of the shopping mall at the Sprawl. The lack of collateral damage from the flamethrower also suggests that nothing is flammable in the far future. Space age materials indeed.
** Clearly, these inconsistencies arise from technical issues. In a game with Dead Space 2's high level of graphical fidelity, it would be difficult to implement a fully destructible environment. What's really odd is that the lack of even cosmetic damage to surrounding structures isn't more jarring than it is.
*** But it is awful. Think about it entire station is unbreakable. Unless something like sun laser is in effect, or giant drill. And yet there they are - fragile windows! Leading to outer space no less. What if someone would accidently fell on them? Brrr...
[[WMG:The Final Boss Fight]]
At the endgame Isaac is [[spoiler:repeatedly impaled by the javelin gun, making whatever health he has plummet like a stone.]] After the last fight is done however, he shows no signs of it. This could actually become a nice bit of fridge brilliance, if it is later revealed he is gaining Hunter/Ubermorph fuck-you-conservation-of-mass powers, and regenerates leading into a storyline of how he's turning into a necromorph human hybrid or how there are two forms of convergence, the Necromorph/Hivemind one and the Badass Engineer/Nerd/Iron Man Isaac Clark version, as well as explaining how he seems to be made of iron even with his armored suit. But I doubt that will happen.
* Watch carefully at that seen again.[[spoiler:He is shoot twice by the Javelin Gun. The first shot got Isaac about 4 inches left of the heart (if you look closely), and the second shot went right through his hand.]] Also remember how much adrenaline must be going through his system, and the RiG suit may have a way of numbing pain without medigel. We never see Isaac about 20 minutes after the game has ended, if we had, he would probably be in serious pain.
** And as I recall his RIG health gone to complete red zone. So that means after Marker was destroyed, his injuries caught up with him. Adrenalin boost wore off and all. And why should we wonder? He can fell from great height, and shrug. A bolt to the shoulder is no biggy.

[[folder: FridgeBrilliance:]]
[[WMG: "Isaac, we're all gonna burn for what we did to you."]]
One might first think that was just referring to the physical torments the asylum's doctors put Isaac through, like the horrible eye-shot that stimulated the memories of the Marker's influence. But it isn't. Keep this in mind: To Isaac, it's only been a few days since the events of the first game. He hasn't had any opportunity to come to terms with Nicole's death; he's still shell-shocked, emotionally drained, still in desperate survival mode, and still clearly suffering. And the asylum has ''deliberately kept him there''. They've been steadily erasing memories repeatedly to ensure that he's in the right frame of mind for their experiments, prolonging his suffering and preventing closure. '''That's''' why they're damned.
** Then add in what Nicole hallucination says near the end, [[spoiler:that convergence requires one last body, that of the maker of the marker to be added to it.]] So not only was he tortured and kept suspended like that for years, ultimately he was to become the [[spoiler:catalyst for making whatever the heck the markers are trying to create.]]
*** Were you reffering that they actually burned in the end, as Convergence started? Because you can see them engulfed in flames.
* [[spoiler:Franco's]] death/transformation into a Slasher is very gruesome but contains one strange element. His face peels open. However most slashers you'll encounter still have existing faces, so why does only he shows this kind of transformation. Well the peeled face effect does appear on other Necromorphs. The Zealots. Slashers made from believing Unitologist. Now consider that [[spoiler:he is a fully devoted Unitologist alongside Diana]] and that gruesome part of his transformaton becomes forshadowing.
** Daina also yells that her "brother" died to get Isaac out of that hospital. Franco's black and Daina's white; the possibility of adoption aside, this is [[spoiler: most likely yet another slip on her part. He's her "brother" in the sense that he belongs to the same order as her.]]
*** That would explain his weird hands, when you kill him several times through the game. Ewww...

[[WMG: The Shop's Wares]]
* Why does the shop sell a variety of engineering suits, and tools to Isaac? Because on his RIG, he's still classified as an Engineer for the CEC. Obviously if there was an instance where he didn't have a tool for a job, he'd have some form of pay allowance to afford whatever tool was necessary at the time (or he'd simply be able to charge the tool to his project's budget). Given that he's not on a job, he has to acquire the money himself to pay for the tools.

[[WMG: Isaac's Willpower]]
* Isaac's HeroicWillpower is much more than an InformedAttribute. Anyone who's played ''Dead Space Extraction'' can see for themselves just how rapidly everyone else in the presence of the marker started hallucinating or hearing voices. Which makes him all the more impressive.

[[WMG: Isaac's Suit and Weapons]]
* Why is it that Isaac, an engineer who has never had any real military training or equipment, been able to do so well against the Necromorphs while the Security and Military Forces have been brutally slaughtered? Simple, it's because Isaac is an Engineer. How do Necromorphs attack their victims?

This would also explain when [[spoiler: Isaac gets attacked by the Security Force late in the game he takes so much damage from them. His suit is designed to resist attacks from something like a Plamsa Cutter or something similar, but it certainly wouldn't hold up to a pulse rifle.]]

[[WMG: Nicole's Neck Snap]]
* How is Nicole able to snap Isaac's neck at the end of the mine level? The answer is simple: She doesn't. Remember, [[ThroughTheEyesOfMadness this is all in Isaac's head.]] He probably ''does'' feel hands grasping his neck, but the Marker's influence on his mind is making him believe it's ''Nicole's'' hand. [[http://www.youtube.com/watch?v=bwMf72fQhno#t=2m17s Video proof.]] Pretend Nicole isn't there and notice the position of Isaac's hands. Rather close to his neck, aren't they. With the right level of nerves and adrenaline (which the hallucination helpfully provides), it wouldn't take much for him to snap his own neck.
