Not OP but I think this needs to be said - it's not that it's a pokemon-like game that just happens to randomly include super out of place looking modern weapons for the hell of it. It's a game with sweatshop labour, eating your pals, pals eating other pals, cannibalism, poaching, death from overwork, all sorts of messed up lore etc. The guns aren't an outlier, they're a fitting part of the game's zany atmosphere
