Overhaul sucks, I can tell you this because I worked on that mod.
If you wanna be impressive about this : Learn some C and recreate the weapons, or install JopoJelly's cave story mod, that one has a few.
Right now the primary interest in the game has shifted from the game itself and what you can create in it to mods, RL is a bit slow with their updates (Somehow worse than Mojang) and is thus kinda bad at keeping hype for the game active.
