* Unmodded Tenno/Orokin weapons provides balanced stats against everything, which destroy Grineer and Infested alike. [[GameplayAndStoryIntegration The Corpus know this from studying Orokin technology]], and so they came up with their counter : lots and lots of energy shields. No wonder Ospreys are so annoying.
** Early-tier Grineer weapons tend to be effective against Corpus: they were fighting them for years before you showed up.
** High-tier or clan tech Tenno weapons usually focus on slash damage which strong against Infested, just like how the Orokin intended them to be used.
* On the whole, the ugly Grineer weapons compare very favorably to the sleek Corpus weapons. Why? Because Corpus are a megacorp and so their weapons are designed by marketing execs for ''sale''. The Grineer are soldiers, and so their weapons are designed by soldiers for ''combat.''
* Excalibur's Radial Blind. In Arthurian Legend, the first time Arthur's reign is challenged, he drew Excalibur and it blinded his enemies, sound familiar?
* Magnetic damage is amazingly effective against Corpus. But then, the Corpus are a faction that consists heavily of robotic and mechanized forces. And we all know what ''magnets'' do to computers.
* Valkyr (TheBerserker warframe) has a skill called "Hysteria" that darkens your vision, forces you into melee-only combat and grants NighInvulnerability for it's duration. [[http://tvtropes.org/pmwiki/pmwiki.php/Main/ShownTheirWork Actual Norse berserkers fought in a nearly uncontrollable, trance-like fury, and some theories suggest they did so by eating drugged food before battle (which also resulted in altered sensorial perception)]]. the Valkyr warframe isn't just emulating how a real berserker would fight, it's also using InterfaceScrew to (partially) give the player a sense of how a real berserker would '' perceive things''.
* All of Stalker's weapon are designed specially to kill warframes. His bow ''Dread'' and his scythe ''Hate'', the two weapons you're likely to face in combat against him, focus on slash damage whose status effect is [[NoKillLikeOverkill Bleeding]].
** A Nikana stance mod Stalker can drop upon his defeat is called ''Blind Justice''. The name probably refers to [[KnightTemplar what Tenno think of the Stalker.]]
* Hek's namesake shotgun deals primarily Puncture damage, making it good against... other Grineer. Not unreasonable to suspect he uses it primarily to dispose of any other Grineer who might try to get in the way of his plans.
* Ordis is a [[MeaningfulName Cephalon]] in charge of operating your Liset. In biology, [[http://en.wikipedia.org/wiki/Cephalon_%28arthropod_head%29 cephalon refers to the head section of arthropods]]. Now look at your Liset again.

* Try not to think about the implications of finding Nano-Spores[[labelnote:*]]"Fibrous technocyte tumor. Handle Infested tissue with caution."[[/labelnote]] or Plastids[[labelnote:*]]"A disgusting nanite-infested tissue mass."[[/labelnote]] on Grineer or Corpus units.
** Or the fact that Medium Team Heal Restores are made of the aforementioned Nano-Spores.
*** ''All'' of the medium and large Team Restores use them. It's possible that once removed from the "control" of the infestation, samples of the virus could be used to replicate material, [[FridgeLogic but that has its own issue]].
* Survival missions are full of this:
** During the event that first introduced Survival missions, there was ''no extraction.'' You fought until you died. How many brave Tenno did the Lotus abandon to their doom?
** Corpus [=MOAs=] are bipedal robots, basically guns on legs, and the only sound they make is an odd warbling noise. But in Survival missions, they sometimes drop personal life support modules. They also do take toxin, gas, and viral damage (albeit less than other enemies). [[AndIMustScream Which means they aren't robots.]]
*** Actually, just because they aren't machines in the normal sense of the word (like what most of us consider to be a robot), doesn't mean they aren't robots. In all likely hood, the parts that need to move the most (the legs) are organic in nature, like the Geckos from MetalGearSolid, and would thus require atleast ''some'' oxygen to function normally.
*** Alternatively, they could just as easily be carrying spare tanks around for the troops like the proposed [=US Army M.U.L.E UGV=]. When one of the troops need more air, and his friendly neighborhood [=MOA=] can supply some.
** Infested Survival missions and the Lotus's line: [[ItCanThink "They've turned off critical life support systems."]]
*** As of Update 15, this is no longer the case in Derelict and Dark Sector survival missions; instead, once the alarm is triggered, you're informed that the Infested are saturating the location with toxic spores. More fitting, yes, but not any more comforting.
** The Corpus can somehow turn off the oxygen generation for their frozen planetside outposts. Excavation has started replacing planetside Survival missions in recent months however.
* The Valkyr is a Warframe that was a survivor of the Gradivus Dilemma, an event where Corpus exec Alad V disassembled several frozen Tenno to create his own special proxy, Zanuka, and the design of her Warframe reflects that. What appears to be some sort of mask is clearly the true form of her helmet, the inside plating quite visible in contrast to the flowing exterior, and a similar section along her spine shows the fine armor beneath the suit. In other places, what used to be the aforementioned organic exterior of the suit has been put back together with makeshift repairs, giving Valkyr's armor a very flayed and raw appearance. Furthermore, the rest of her suit is studded with pins, some of which seem to go through her arm, which could potentially be holding what's left of her exterior together. Combined with the obvious restraints that she now uses as weapons, and the constant anger and rage she barely keeps control of, and one can only imagine what horrors the Corpus did to her...
** Though it's also a case of FridgeLogic if you see Warframes as classes of armors worn by Tenno rather than each as a unique character. Because it would mean the Tenno essentially replicated a terribly damaged frame including replicating restraints that go through the arms of the wearer.
** The 'Valkyr's Bonds' syandana's description mentions that it was made in memory of the torture the original Valkyr went through. It could be that the Tenno, being big on honor, consider impaling themselves in the same way she was another way of remembering her pain. Alternatively, it could be that the recreated Valkyr armor's restraints only appear to be going through the arms. Or maybe what the Corpus did was somehow responsible for Valkyr's incredibly high armor strength, and the Tenno thus copied it perfectly.
* Rescue 2.0 (introduced in Update 13.2.0) has Infested in prison cells. It's possible that the technocyte virus works so quickly that some random civilian, insubordinate Grineer, Corpus POW, Red Veil member, etc. was thrown in just 1 minute ago, and transformed into an Infested in as much time.
** It's equally possible (and potentially proven, by a recent Infested-themed questline) that the Infested are in the cells as captives for research purposes. The lengths they must have had to go through to take one of things ''alive''...
* The only indication that "synthesis scanners" you get from Cephalon Simaris are lethal is when he randomly starts talking about the ethics of murder and UnwillingRoboticisation out of nowhere, without anyone prompting him to. Considering nonlethal scanning/teleportation devices already exist, for Capture missions, that's a pretty big thing to leave out of the briefing document.
[[folder: Fridge Logic ]]
* The event entry for the end of Arid Fear has Vor note that "reactive dissolution" hides the answers about Warframes. Considering that the Sentients turning the Orokin's own technology against them was a huge problem, it makes perfect sense that the Warframes would be specially engineered to prevent anyone meddling with them from learning the truth about them.
** Which apparently doesn't work very well, considering Corpus dealing in ''Warframe parts'', explicitly showing how they're obtained in the PS4 trailer, and Zanuka boss/miniboss being made of said parts.
** Maybe because the Corpus are working from (admittedly hamfistedly-reversed-engineered) the orokin's own tech, and the Grineer mostly use much more crude tech that they developed themselves? or maybe Alad V's lack of problems with dissolution is plot-relivent at some po- oh god. what if the dissected tenno's warframes didn't self-destruct because they never DIED?
*** Which makes Zanuka/Harvester even more troubling.
* One of Captain Vor's comments in the Prologue section of Update 14 implies that the Tenno do not just wear the suits around them, which give them unique powers, but are, in fact, beings of energy that rely on the suits for containment. While probably just the incoherent ramblings of an Orokin-obsessed madman, or excessively-metaphorical language, this could provide a logical explanation as to why the Warframes can manipulate the elements, create antimatter and gravitational shifts, conjure up nanobot swarms and ablative armor from nothing, and even why their "health" pickups are so similar to their energy pickups. The Warframes themselves are symbiotic conduits for their energy-based users, changed by their exposure to the Void, that let them channel that energy in specific ways.
** Wow. That is... that makes absolute sense to me. It would explain why we never see the Tenno out of their Warframes, as well as the other things you have mentioned.
** If I remember correctly, Vor's wording is. "The Tenno don't somehow control the divine light that gives them such powers. They ARE that light!"
*** Specifically, the full quote;
-->''""We've been wrong all this time. Tenno do not control the Warframe's divine energy. The Tenno ARE that energy. Each Warframe you control is merely a glass shaping your furious light." "''
** The only question that brings up, though, is why the Tenno bleed when they take slash damage?
*** Rhino Prime codex entry implies that [[spoiler: the warframes are built around those who were sent into the Void.]]
*** My theory is that Warframes are, in fact, a human or at least... [[HumanoidAbomination humanoid]] body and a suit of armour built around them, as one composite unit. They are missing most of their consciousness if a Tenno is not presently occupying them.
