FPS games are almost impossible on the iphone. Cube and silent hill come pretty close. I think half dead comes the closest control-wise. Basically, the controls go like this: In the bottom left corner, there is a dpad/joystick that controls movement that you drag your finger much like hero of sparta, BIA, etc..... In the bottom right corner, you have a virtual dpad/joystick that controls your gun and where you are aiming. You can either have a seperate button for shooting on the left side much like half dead or it can automatically shoot when you look around with the right joystick (you would have to have lots or infinite ammo). This is exactly like control scheme 2 on BIA. This is pretty much exactly like half dead but you can't move side to side in half dead. If only they would add side to side movement in half dead, it would be so much better. Same thing with cube, if only they would make their accelerometer movement less sensitive so you could walk and not run all the time (i guess it is supposed to be like quake so i understand that) or a dpad for movement in the bottom left corner. Im not sure about livefire's controls. This is pretty much just combining half dead and cube and i guess some BIA as well. Your thoughts?
