I liked it, a good game. Difficult at times. Hated the long loads when dying, a lot. Sucks that the difficulty achievements don't stack, so I played it on the first one. Did get all the weapon achievements and also the 3 hidden [saving squad's] ones... will play the other difficulties one day.

Fascinating!

i really liked Quake 4. I was an enormous fan of Doom 3 and this had a similar feel. Not as good, but still fun.
