Heli attack is a bit of perplexing game. On every mode you will have to press a new switch for a new weapon or for jumping high or crouch down a wall. But the best thing is that you don’t have to search for keys. Instructions are always displayed as you pass by the path where you have to jump double or have a new weapon. The game is all about destroying the intruders coming along your path. Keys A and D can move you ahead and backward. Press W to jump and S to crouch.
