Rip and tear until Morgana is done!
Weapons are kinda already in the game, in that both MC and Gramps have been shot at before. If you mean as part of the battle system, it's getting a rework. No guns for MC but lots of weapons for his opponents!
Ah, damn. I was gonna ask if you could make a reference to DOOM or something.
Yes, my only objectives here are to recommend references and try to have fun
