I just bought Doom on Steam the other day. Loving the out of control monster spawning. It definitely moved back into the category of fast-paced "blow shit up" vs survival horror, but ID also managed to do it in a way that still requires strategy - Mainly that you can't stay put or you'll die, and you've gotta be good about your ammo.
This layout looks like it is going to be similar in pace. A think a cool idea for a pin like this would be some sorta timer that prevents you from taking your time with shots or holding a ball too long, not just a mode/score timer. Flipper hold > 5 seconds = flippers/lights off + death sound
You should also put a microphone on the game so the high-scorer can record a sound sample that plays back and gets used in the game as a taunt.
