I have an idea but I don't know if it is possible: play with a normal keyboard + mouse and at the same time have the rumble/force feedback effects from another controller which is supported by the game. This could offer some cool posibilities by hacking a gamepad with rumble effect, such as turning on and off a big red light behind your monitor when being hurt, or using a big motor to shake your whole chair, or some electric shocks to your body hehe.
