Mega Monster Mix
A downloadable mod for Windows, macOS, and Linux
The Mega Monster Mix is a Doom gameplay mod where all classic monsters are replaced by a Mega Mix of Monsters, ranging from 5 tiers of difficulty with 450+ unique monsters already!
- Tier I: Basic versions and WEAK versions of the original species. Fodder pretty much.
- Tier II: Majority of the monsters, SLIGHTLY more difficult than the normal versions.
- Tier III: Pretty tough compared to the usual monster, a lot more difficult or special.
- Tier IV: The F- You tier. Low chance but if they do spawn you're in for a bad time.
- Tier V: Minibosses, so different and difficult they are announced at the start of the level (inspired by Colourful Hell), though this can be turned off if prefered.
This Mod is NOT easy nor is it fair and balanced, especially in harder Wads and Mappacks. Monsters drop items but hefty weapon packs are recommended. Weapon packs like:
- Trailblazer
- Hellrider
- Mobian Warrior / Princess of Rebellion
For even further chaos, the mod is made compatible for Corruption Cards.

The mod is excellent, I love it. It's perfect for slaughtermaps or when you want a great and challenging variety of enemies. My only complaint is how horribly optimized it is. It lags easily with more than 10 enemies, and when you activate the freeze command, it lags progressively until it drops to 2 FPS. That's the only bad thing I've found about the mod; the rest is incredible. Keep it up!
Over 450 enemies? Yeah, I'm definitely playing this, I love it.
Very fun mod, hard, but fun.
Whats new in v1.1?
EDIT: nvm, I saw the zdoom forum post:
Compatible with gzdoom 4.8?
