Yeah, one or two of those look fake to me... then again, it's a long way off, so.. If it's real, some of their Stroggs inspiration seems to have come from the Borg in Star Trek... god, I hope this isn't going to be Star Trek without the official license:(
As for corridor shooters... I'm the biggest fan of UT2K4, but that style of game with per pixel hit detection would be a pain in the ass.... would be chasing and trying to kill one friggin person forever, unless the railgun is in and a one hit, one kill weapon. Some open areas are nice, but some inner areas where you do actually have to fight if you find your opponent are needed, I think.
Interested to see what Valve do with this and Half Life 2... I think it's probably part of the reason CS was added as the main mp element.... will take an entire platoon shooting at one person at a time to kill it with this pixel hit stuff... DooM3 is slow, so it works... but I much prefer Quake 3 or UT2K4, both of which leave me laughing, sweating and feeling like I've run a marathon after a good battle...
