interaction and controls: Control is done via stylus, D-pad and shoulder buttons. The stylus is used to aim with your weapon while the D-pad is used to control the character. Therefore the player can walk and shoot into different directions (like Berzerk). Shooting is done via the shoulder button. Weapons are changed by either taping a weapon icon in the corners of the touch screen or by using the four action buttons. The characters are NOT able to jump. It's not a necessary feature and jumping always implements potential problems. Maybe they could have dash-moves like in Silent Bomber or some other special abilities.
