Lately I've been searching for free (or at least really, really cheap) First/Third Person Shooters that can played offline against bots, preferably with a modern or sci-fi military theme and no extreme gore (blood is fine, I just don't want ultraviolence like people getting blown apart or anything with Zombies and stuff) nor any um... "adult" content, if you catch my drift. Anyone know any good ones that fit this description?
Fistful of frags is good fun, it's cowboys though not sci-fi. I don't think it has single player but you can do a private server with bots.
Also jedi academy multiplayer can be played offline and there's some good mods or if you want a story half life 2 and uncharted (ps3) are great games and cheap.
Command and Conquer Renegade was my go-to FPS game when I was a kid. Pretty sure you can get it for dirt cheap on Origin.
Alternatively, an indi group made a sequel called Renegade-X. Both are great games if you want to try them out.
