Game Recommendations

[zero_kanipan]

necro mode!!

anyone got recommendations for good old FPS games for PC? again something around HL2 engine or lower since my laptop sux. (Core 2 Duo 2.0ghz, GeForce 9300M GS 256mb, 3GB RAM)

stuff i've already considered but have decided against:
elder scrolls series - sloooow. also i want guns
fallout 3 and up - laptop can't handle it
borderlands - laptop can't handle it
stalker series - runs a little too slow. also, playing it mods before ruined my taste for vanilla stalker. said mods are missing from my drive T-T
hl 1 and 2 - not these again, although mods/maps for these are alright
the fps mentioned earlier in the thread - as i mentioned, i've already played those games.

what im mostly looking for is something that's the game equivalent of a "quickie." get that itch to go and shoot/kill stuff. run the game. play an hour or so blazing guns or whatever weaponry, then go on with the rest of my life ^^ one vs lots of enemies is also nice. plus points for dynamics (every run through can be done differently.) actually, Left 4 Dead is a prime example of what i'm looking for. just sucks my laptop can't run that game properly anymore.

of course, stuff with a plot or story is also welcome. stuff like half-life, doom, etc.

oh, and since my net is retarded, multiplayer only is not really ideal.

games i'm currently considering:
quake 3 arena - still looking for a download
CS 1.6 portable - still looking for a download
F.E.A.R. - still looking for a download. i never get tired replaying this XD
Unreal Tournament 2k4 - i have too many mods with no install guide -.-
H.A.V.E./MicroVolts Online - dunno if the pc/net can run this decently

looking forward to your replies o/
