History Recap / QuakeIIHangarUnit

* AbilityRequiredToProceed: In the PC version:
** The Commander's Head in "Research Lab" unlocks the access to "Inner Hangar" from "Outer Hangar".
** The Red Key in the stress testing area of "Research Lab" unlocks the access to the medical facility where the damaged Tank Commander is located.
** The Airstrike Marker in the bridge of "Outlands" is required to take down the Black Hole Generator and unlock the entrance to the City Unit.

** The Commander's Head in the Research Lab unlocks the access to the Inner Hangar.
** In the Research Lab, you have the Red Key in the stress testing area, which unlocks the access to the medical facility where the damaged Tank Commander is located.

** In the Research Lab, you have the Red Key in the testings area, which unlocks the access to the medical facility where the damaged Tank Commander is located.

* SawBladesOfDoom: Present in a small room in the Research Lab. It kills the lobotomized marine in place.

* AnvilOnHead: "Comm Satellite": It's possible to take down the Hornet without firing a weapon. Just make sure he ends on the receiving end of the falling satellite dish. It:s a bit hard to do in the 2023 remastered version, as the Hornet ''can'' escape the falling dish.

* BrokenBridge: Access to the next unit is locked behind a door that must be blown up by the Airstrike in the "Outlands" level.

* DoesThisRemindYouOfAnything? The "Research Lab" level involves countless prisoners being subject to horrific experiments, in a pretty obvious reference to the Nazi's MadScientist experiments in concentration camps (which ties into their whole "Space Nazi" theme, as mentioned under ScaryDogmaticAliens). While this game doesn't go into detail on what the experiments involve, ''VideoGame/QuakeIV'' (which follows the storyline) claims, at one point, that prisoners [[CruelAndUnusualDeath sometimes have random organs removed to see how long they'll survive without them.]]

** In the "Research Lab" level, there's A.H.D.S.S.I.B.H. bjjc[[labelnote:Explanation]]"A Hall Displays Secret Snapshots In Boss' House". "bjjc" stands for Brandon James & John Carmack.[[/labelnote]]. In order to get the Egg, you must kill all of the prisoners located in the level. Once this is done, return to the entrance of the level where the two glass windows are, when you'll see the left window now has "kill me" written on it. Break the window and enter the chamber, where you'll quickly find another prisoner behind glass which displays the message.
** The 2023 remastered version of "Outer Hangar" has a new secret: in the poolyard outside of the entrance to the SecretLevel, there's a new piece of rock sticking out of the rocky walls. Shooting this piece will cause a flag to destroy a small portion of the wall, revealing a hidden windmill, a hockey stick (too big to be a golf club) and a small ball.

* FasterThanLightTravel: The Black Hole Generator creates [[UnrealisticBlackHole Unrealistic Black Holes]] which allow the Strogg to travel to other solar systems. As such, destroying it (which is one of the main objectives), will prevent them from sending reinforcements to Earth and leave them stranded until they can make a new one.

* PermanentlyMissableContent: The initial fan control room in "Inner Hangar" can be revisited until the computer which controls the fan is turned off. [[ButThouMust This is, of course, necessary to proceed to the lower floor of the area]].

* AnvilOnHead: "Comm Satellite": It's possible to take down the Hornet without firing a weapon. Just make sure he ends on the receiving end of the falling satellite dish.

* DeathCourse: "Outlands" is filled with Weapon Guards, Barracuda Sharks on the big lake, Flyers, and Enforcers (only at the very end there are Gunners). It also has one of the highest enemy counts of ''II''.

** The 2023 remastered version of "Outer Hangar" has a new secret: in the poolyard outside of the entrance to the SecretLevel, there's a new piece of rock sticking out of the rocky walls. Shooting this piece will cause a flag to destroy a small portion of the wall, revealing a hidden windmill, a hockey puck and a small ball.

* VideoGameCaringPotential: Putting all of the prisoners out of their misery in the "Research Lab" level is required for its Easter Egg. [[GuideDangIt Not that any guide will tell you that]].

* EasterEgg: In the "Research Lab" level, there's A.H.D.S.S.I.B.H. bjjc[[labelnote:Explanation]]"A Hall Displays Secret Snapshots In Boss' House". "bjjc" stands for Brandon James & John Carmack.[[/labelnote]]. In order to get the Egg, you must kill all of the prisoners located in the level. Once this is done, return to the entrance of the level where the two glass windows are, when you'll see the left window now has "kill me" written on it.

* EasterEgg: In the "Research Lab" level, there's A.H.D.S.S.I.B.H. bjjc[[labelnote:Explanation]]"A Hall Displays Secret Snapshots In Boss' House". "bjjc" stands for Brandon James & John Carmack.[[/labelnote]]. In order to get the Egg, you must prevent the death of the broken soldiers in the level, which involves taking care where you shoot, preventing enemy fire from reaching them, and NOT triggering any of the torture devices. Once done, exit the level and re-enter it, and break the first glass ceiling.

** The level "Comm Satellite" takes place in a spaceship. At the beginning and end there are two areas marked with red warning stripes. Stepping onto them launches the player to outer space without protection with the expected results. The areas can be safely walked if the player had the foresight of closing the bay doors first.

** All over the place in "Research Lab". Suffice to say, doing the steps required to trigger the EasterEgg becomes a SelfImposedChallenge:

* VideoGameCaringPotential: Not executing the prisoners in the "Research Lab" level is required for its Easter Egg. [[GuideDangIt Not that any guide will tell you that]].

* BatmanCanBreatheInSpace: "Comm Satellite" requires the player to deactivate some stuff... inside of a CoolStarship with open windows and entrances/exits.[[note]]The bay doors will [[ExplosiveDecompression launch you into space]] if you get too close, killing you instantly.[[/note]] The detail? None of the original models/skins which shipped with the game included any space suit.

* BrokenBridge: Access to the next unit is locked behind a door that [[spoiler:must be blown up by the Airstrike in the "Outlands" level]].

* EasterEgg: In the "Research Lab" level, there's A.H.D.S.S.I.B.H. bjjc[[labelnote:Spoiler explanation]]Stands for "A Hall Displays Secret Snapshots In Boss' House".

* CompressedAdaptation: The Playstation version compresses this unit and "Big Gun" into a single unit, and culls off most of the levels, to the point of leaving only three of them.
