Choose the mode
Version 1.0 defaults to Keyboard & Mouse, with free mouse aim and assignable mouse buttons. Settings retains Keyboard-Only Mode; its menus still accept mouse input.
Check the result
After changing the mode, test aiming and one assigned action before committing to a fight. A clickable menu alone does not tell you which combat scheme is selected. Use the displayed assignments for your configuration; this guide does not invent a default key map.
