Finally decided to have a go and I have now been stopped in my tracks by the 'lost korean' bug. It's at the end of the level where you are waiting for extraction by vtol, but they can't land because the LZ is hot - kill all the guards and 4 of the Koreans in nano-suits - but the jet doesn't come - seems like the 5th guy is invisible/hiding/didn't spawn and now I can't progress.
First time I've ever come across a broken FPS - really is pretty p-poor in my book - not even like it's a complex multi-threaded rpg quest-line or anything. How hard is it to:
1. Spawn enemy
2. Kill enemy
3. End level?
