About Temple Of Boom
How about playing an action game in 2-player mode? Yes, you can play this action game alone against a robot or you can play with a real human. You will need an additional keyboard, though to make the control comfortable for both players.
You start playing, you will be asked whether you want to play in the Campaign mode or endless mode. Choose any of them you like.
The control keys will be shown right before the game start. So remember them or take pictures or note them down.
