This started out as a superpowered flamethrower. Then I added a BOMB gun, and it sort of went from there. I had a laser sight before, but I found that some of the artillery, namely BOMB, conflicted with the sight and exploded on contact.
A few notes before you play: It's a bad idea to fire the flamethrower with the BOMB gun. It gets messy. Oh, and if you apply fire to the photon cannon on the top, everything gets destroyed by the escaped REPL. So, uh, beware!
Well IMHO, I think it would more multi-purpose like if you added something like freezing cannon that releases absolute-zero photons or something... BTW, I realized that you could replace the PLSM clones with WTRV clones and it still works, but it release super hot WTRV like a geyser.
