Like other people have said Unreal Tournament is your best bet. It's the most smilar FPS I can think of to Halo but faster.

I would buy Haze if I was in your position!! =P

How about KillZone 2? to me, there is no better than KZ2

killzone 2 is good dont get me wrong but its more a realistic shooter than scifi shooter i want something a little more jumpy/more bullets to die type thing

Everyone has personal preferences. Honestly there are tons of better games than any Halo game. That's my opinion anyways.

I would recommend CSS to anybody who is looking for a shooter. But I see you are already playing it. A lot of people recommended UT3 but UT2004 is waaaay better more people play it.

That's true, but it depends on how much Dioxinis care about the game graphics, UT3 is still a very good  game, following that argument UTgoty ed of 1999 is even better, in my opinion.

Halo is the best in the business. I say just pay the $ and get an xbox and Halo 3:ODST and then youll get in the beta for reach that starts monday. Theres never been a better time to jump in

well im torrenting unreal tournament 3 to try it out since im not sold on it just yet (dont bash me for piracy money is tight right now and i cant just buy it on good faith so im TRYING THE GAME)

but if i like it i'll buy it on steam... and if i REALLY like it i'll buy the unreal pack since people say the older ones are better and i'll be able to try all 3 and stuff like that

Sorry for being repetitive, I think you should torrent UT1, it's only about 700mb, it takes much less time, and you would have a good idea of what UT3 is, almost the same game with better graphics but less arenas.
