As far as I know, there aren't any, but there's a pretty good FPS called AssaultCube that doesn't need any downloads OR administrator privileges. One more perk of this is that you can modify the game (only for you to see)! Happy cubing!
Red crucible 2 is pretty boss
I find a reasonable game (It is hard to find a great online FPS without downloading) to be a game called Russia's Army. It has 8 player online with a selection of weapons and a nickname. You can find it here: http://www.gamevial.com/russiasarmy.htm
if it isnt satellite or dsl then yes its an amazing speed for any online game
the best fps in my opinion is called halo trial you get campaign and multiplayer also you can download really cool mods you get the game at download.com get on the Internet and try it out the game is really fun
It is just a fun FPS (first person shooter).

phosphor, paintball paradise, and orange fps
No i have download many skins never had a virus :)
a good gory fps title would be dead island not sure how long the campaign is tho but it is a game that does take quite a wile to play though
It would have to be FPS because FPS games are more interactive

Despite popular belief, Wolfenstein 3D and Doom were not the first FPS games in history. An FPS game called Catacomb 3D predated these two games. It was the first ever FPS game in existence. But you used magic, not firearms. It was an OK game. Released for PC and NES (maybe more).
