 Behind the scenes
- Stacking a few props makes it possible to get on top of the combine side (for Team Deathmatch) bunker entrance. This trick allows one to survive the airstrike undamaged while being outside the bunker.
- Using the "noclip" cheat reveals an inaccessible sewer tunnel between the docks and the drainage ditch. It was likely supposed to connect the two areas for a better map flow, as the drainage ditch is a dead end, but was left blocked off for some reason.
The Combine control panel used to call in airstrikes.
