This was the first real gaming/machinima film I ever saw although it's also kinda a frag movie. It is still my favourite. At the time I was heavily into Counter-Strike and was very good too (although this is 1.6 and I mainly played Source in my Counter-Strike years, I did play 1.6 for a while).

The things these guys managed to do/level of coordination in official matches/wars was very impressive and at times very very funny add to that awesome production & music and you have a great video:
