Half Life 2
Half-Life 2: Garry's Mod Insaneity Map
This is a good gmod map by H2 NooB. It appears to be based in a complex with a bloodied swimming pool outside, inside there is a large chamber encircled with water (The ion kill room) which will
destroy everything within the chamber, and this can only be activated in the [i]Admin-Room[/i], this admin room is different from other maps, if you are not the admin you cannot enter it, no vents, no hidden teleporter, you cannot enter unless you are the admin! The Ion Cannon cannot be activated without four power-units which are next to it. There is also a "Changer" that turns melons and oranges into grenades, just plop them in and watch them transform, this map has quite a few other nice little features in it also. It is well textured and has had alot of effort put into it, well done.
