I need a good single-player FPS

Okay, so I'm not going to have gold until this Christmas, but I do have some spare cash lying around.
 
For the Xbox 360, is there a good single player FPS on the cheaps? I'm thinking about buying the orange box but I'm not sure I'll like it. Should I just get the Orange Box, or is there any others that are better? Thanks.

Well, what do you like in your shooters?

I've never played Half-life but I think I will buy it after some research.
 
Also, I would pay 20$ just for Portal. So I hear.

Orange Box is a great idea. Its got all you'd want in an FPS. But it's a bunch of FPS's! All the half life games are an astounding mix of both action and puzzles, Portal is just plain kooky and puzzling, and TF2 is well, TF2.

I like when there are enemies to shoot and guns to shoot them with. "

BioShock, Orange Box, and many, many others out there. FEAR 2, if you don't look at it too hard.

Bioshock...the Darkness is pretty good too, although I suddenly stopped playing it one day out of the blue. : /

I already have Bioshock. 2nd favorite game I ever played.

FEAR 2.

I'd have to agree that the Orange Box is the right choice.  Tons of content for a great price.
Also, The Darkness is amazing as well.  You know what? Buy them both...

Call of Duty 2 for like $10 ? lol

The Orange Box is a must-have. If you don't have it, you should solve that problem right away. :D

I won't argue with The Orange Box, but if you have enough left over get Quake 4. It got vastly overlooked, though it's pretty solid.

I bought Orange Box for £25 (about $40 I think) and would be willing to pay double that as 5 games which are all some of the best games ever made. Half Life 2 simply has to be played and Portal is genius and when you do get live TF2 is as replayable as any online shooter. I say go for Orange Box.

The general consensus is that Orange Box would be a great for you, and I concur!

Fallout 3 has more gameplay. Also it is better.

Bioshock!  Can't recommend it enough, it's a great game.  Intriguing environment, some pretty cool abilities and a great story make it a hella good game.

I just finished Call of Juarez: Bound in Blood, and it was pretty fun.  You might like  it too.

Orange Box. Don't know about other cities, but it's $20 here in Southern California.

Orange Box. Bad Company and Rainbow Six Vegas are also good if you have extra money left.

Definitely The Darkness. Also, Call of Duty 4's single player campaign is freaking absolutely amazing. It's not all that long, but definitely great enough to replay a few times. Bioshock is a must-play too. If you're open to an FPS RPG, you can't go wrong with Fallout 3. I think it's a truly remarkable game, but it might not be quite what you're looking for.

I would say Fallout 3, just for shear scope and length of the game, and Orange Box for some variety.
