Hi! Thanks for buying it! By SMG I'm assuming you mean submachine gun? Otherwise it is a term I'm unfamiliar with. You can build the primary gun into a rapid fire weapon by activating several coolant pumps. I appreciate the kind words, and have not played One More Dungeon myself. As I'm working on a sequel to CTHON, I'd love to know what you felt was better executed here. Thanks again!
Cthon is smoother, less buggy, and and not trying to do the Diablo “hand” gimmick like 1MD. I hope in the sequel the pumps and such won’t be weapon specific, and that you could spend coolant-mana in addition to ammo. I’d like you to also publish a core data pack for GZDoom, which could be used with any level generators available for the engine.
