I love the style of Invasion, Teddy hunt, Classic and even the Minimodes, but would it be possible to make few of these for Single player? There is always that time you want to play with the AI instead of real players because some online players are hackers or even cheaters that makes you very frustrated getting rid if them . So would it be good to add singleplayer invasion/classic? Plus Teddyhunt and Domination?

Those are PvP modes and we are not planing to make modifications for those to suit single player. You can host such modes per dedicated server and play alone against the bots if you wants. Shouldn't be very interesting though.
As for the hackers and cheaters you mention, we are not aware of such, so if you have any concrete details let us know.

Thanks JackMayol for your reply! Ill take your advice and report any cheater/hacker I see!
