That one's great. Harkov I think it was. Really well done, and the buildup in earlier parts through cutscenes and the secret missions was perfect.

A favourite bit is in Timesplitters: Future Perfect, where you keep entering a time portal in the same room and end up with four of 'you', and each time you step through you have to perform a different task while the other you's do what you did earlier. Awesome.

All-time favourite? Facility, in Goldeneye 64. That was FPS perfection.
