offline mode options?

[WARLOCK]

what are the different modes you can play single player offline?

is there anyway to set up an a.i. deathmatch and play against just computer opponents for practice?

p.s. does your rank in singleplayer count towards your online rank, or are they 2 different ranks?

Arcade mode, regular single player.

No.

You do have semi-ranks amongst your friends for arcade mode, but they don't count towards anything.
