suggest some fps for lan play w/ bots

[speedyguy]

m on vacation n hv been outta touch wit pc games for abt 5 years now so no idea which one 2 go for....

i hv some frnds who can join me on lan games so plz advice some good multiplayer shooters...n ya my pc NOT so new....so very recent ones wont work (p4 1.8 ghz, 512mb, 128mb ATi radeon external graphics card - 9200SE, 100mbps lan)....CZ works well in mine...

it shud have bots (like CS condition zero) as we r just 2-3 guys connected to lan and shud hv some mission....condition zero is good but played that a lot...is there any other names?

thanks in advance...

Enjoy~!
