Sci-Fi FPS Reccomendations?

Blacklight Retribution is okay, but it plays too much like a call of duty with giant robot mode, the community is meh, and the equipment is pay/grind to win. Outside of that, it's good to dump a few minutes on here and there.

Battlefield 2142, but I dont know if it someone playing it.

RAGE

Syndicate

Deus Ex Human Revolution

Far Cry 3 Blood Dragon

Hard Reset

Borderlands 1 & 2

Crysis mebbeh?

System Shock 2

Alien vs Predator (2000 version)

-Hard Reset (not much story there but the gameplay is so much fun and the graphic style is cool!)
-Singularity (great game, amazing atmosphere, interesting story, interesting time manipulation mechanics)
-Doom 3 (sure, alot of is is horror or whatever you wanna call it...for me it's one of the scariest games, scarier than most of this "wannabe scary horror games", but it happens on Mars and has sci-fi in it for sure, great game)
-Crysis 1&2 (well, okay games, great graphics)
-Bioshock games (well, not exactly sci-fi but still amazing games in every way and ofc recommended)
-Half-Life games (great games, intelligent sci-fi)
-Prey (not so great story but some interesting mechanics)
-Deus Ex Human Revolution (haven't played it)
-Rage (haven't played it)
-Borderlands 1&2 (I have played the first one, it's pretty good but gets repetitive)
-Aliens: Colonial Marines (haven't played it)
-Natural Selection 2 (haven't played it)

There's alot of TPS sci-fi games also.
