Thanx for reply. I plug controler before start game. I see it on control panel and can check buttons there. And the game allow me to play with it buy with 2P only (as co-op join) only. I see X360 icons like ("A" or "B" for buttons) but i really wanna to test it with pad, because so far i have seen (few minutes as co-opted player) on pad its awesome and I would like to buy on steam to play.
But im not sure how to play on pad as 1Player and dont want to buy without possibility to play with my gamepad .
When I join as 2Player co-op by gamepad, 1st still works with K+M.
So TL:DR : can play by gamepad as 2Player co-op, cant as 1P (game doesnt react to pad).
