What first person shooters have bots on the PSP?

What first person shooters are there on the PSP that support bots* in deathmatch mode? The best I've seen is Quake 1 Arena, which uses the Quake 1 engine but has the weapons and power ups from Quake 3.

What others are there, be they homebrew or commercial?

Thanks for any replies.




* By "bots" I mean computer controlled opponents, so that you can play the game without other humans playing.
