One player use wasd one use arrow keys press certain keys to spawn attackers defenders and more, They will follow your checkpoint path if they are attackers and kill the base slowly, Combos are the most op thing in the game press multiple keys at the same time to use them, if you want to see what you have unlocked and what it does hold space to be able to view the list.
Everything by me inspiration from my strong love of battle and 2 player games.
