I was playing around a minute ago with a level someone on here made. Can't recall exactly who made it, but it was a huge tower, which I promptly tore apart with rockets.
I made a (failed) attempt at making a sort of rocket launching device to destroy the tower, so it prompted me to see what everyone else had made as far as amusing weaponry, rocket launchers, tanks, etc etc... Feel free to attach specific levels or to just describe your ideas in general. Thanks!
I'm a chronic tweaker. Three hours of moving one node to save $2... Definitely worth it.
