I've never played Halo.
the only FPS game(other than minecraft, which doesn't really count) that I've played is black ops.
I suck at it(died 10 times in 10 minutes
)
as a consequence, I've stayed away...
EDIT: I just noticed that call of duty is abbreviated COD:

I bet that COD would be much more fun to play than the shooter 
how would you play a cod?
tail- joystick
eyes-A and B buttons

open mouth to insert cartridge
