Ever thought about Russian Overkill 2? Or DoomRL meets Russian Overkill?
Well there's that, nowadays rather obscure, roquelike Nuclear Throne. Tons of weaponry, from simple but effective sledgehammer or a shovel, through different shotguns or Sluggers which fire a massive short-range bullet bigger than itself, or anything it's shooting at for that matter, to nukes and other fuck-everything weapons. Especially when including Ultra Mod which for this game is basically Russian Overkill, or should I say even more than that because I'm not sure if in RO there are full-auto triple nukes, ION cannons and laser weapons that lag the game even though it's a 2d pixelated roquelike, and that's
just a tip of an iceberg. Yeahh the point is the weaponry is bigger than any DOOM mod I was able to find.
I know many people already think Russian Overkill is too much (because it is) but I just thought it's a fun idea. I struggle to think what could be more "overkill" than this, it truly would be an ultimate overkill.
Also, in a way I find the style of both games kind of similar, the graphics and style of Nuclear Throne is very simple and could be easily recreated in DOOM, and probably even enhanced, there are also a lot of cool, well hidden and rewarding secrets (completely separate areas/levels kind of secrets, like golden room filled with weapons or Ninja Turtle hideout...) bosses, many playable characters etc. Even that without the weaponry I think would be fantastic for DOOM, in my opinion it fits very well. The themes, style and overall dodging bullet hell and "rip and tear" style through hordes of enemies, maybe it would reguire some time to play through Nuclear Throne to get that feeling, but for me, it really seems like it would be a leathal chemical reaction, in all the best ways.
Also I should mention, I've never done any modding of any kind, me play game shoot enemies good boom ohohoh
