I did not mean actual guns, I mean like there is a gem in the ground and you have to stop the shy guys getting it, by firing eggs at them or a water pistol, but the area is like a theme, so there could be a horror theme, where boos block your attacks and undead shyguys and ghost shyguys appear, you can move around a bit and try to avoid things like the wind blowing your eggs of course, if a shy guy gets the gem, that team looses, it gets faster and more appear the greater the difficulty.
