hi what joystick can i use for this game ?
You can't. But you can post this idea here. For now you have to stick with mouse and keyboard.
can I use my ATK3 game controller for this game?
Tanki Online doesn't support game controllers to play the game. You can, however, play the PC version of the game using both a keyboard and mouse or simply a keyboard alone, and the touchscreen feature in the game's Mobile version.
