A good First Person Shooter with a good level creator

I was wondering if anyone knew of a FPS with a good level creator

1. Crysis, the level editor is insanely easy to use.

2. Counter Strike, Day of Defeat, pretty much any fps on the hl2 engine has a pretty easy level editor called source sdk.

3. Unreal Tournament 3, little bit harder than the top 2 but thats because i have more experience in the others.

If you are looking for single player level editor it gets more complicated since you cannot directly modify the game without screwing something up so you have to create a completely seperate mod/level.

Arma 2 is supposed to have a crazy awesome level editor.

I highly recommend Hammer (Source editor), one of the easiest modern level editors. You can download it for free on Steam if you own a Source Engine game.

Far Cry 2

There's really nothing that tops it.

Ya i know about Far Cry 2 map editor i used it for xbox360 the only problem is i dont like the game that much the character movement is too slow and only allowing 6 vehicles per map really limits bigger map designs.

Half-Life 2 or Unreal Tournament 3.

Far cry 2 is different on the pc. The only reason vehicle limits were capped because if they allowed you too put more in the system couldnt handle it. On pc there is no limit. Ive built race maps before with 10+ vehicles. Its actually IMO one of the best lvl editors out there.

Did not know that i might have to give it a try
