skip that one, the rest are good.
At least I think Extraction Point was decent, been a while.
Extraction Point's OK until it goes off the rails and kills a major character in a way that's so horrible and prolonged that it finally becomes hysterically funny. It's not "canon," for whatever that's worth, but it's more FEAR and that's all right.
Perseus Mandate looks and feels like a middling amateur Quake 1 total conversion, given a coat of fresh paint and crudely mushed into the LithTech engine. There is a small handful of fun moments, but the rest is like Plan 9 From Spooky Space.
I'd tell about the others, but just have fun! And make sure to look up community patches for Bloodlines, they make the game fantastic.
