This is a single player Half Life 2 mod, set entirely outside of city 17.
+ 6 levels of action, exploring a range of locations (from an underground facility to fighting alongside the combine on an alien world to floating color-coordinated cubes)
+ Non-linear level progression- you start near a nexus of gateways, and may choose the order in which to progress through the levels
+ A musical score (a total of 8 tracks)
+ Some new abstract textures (see image 3)
+ Challenging gameplay - this mod is meant for those who have already completed Half Life 2.
****For those with version 1.0, to get around the bug in the airboat-sequence, just noclip through the floor. (this is fixed in version 1.1) To noclip, open the console with ~ (or if its deactivated, go to options/keyboard/advanced to activate it) then type in "sv_cheats 1" and then in a separate line "noclip" (it should spit back at you "noclip on"). Type "noclip" again to deactivate noclipping....
