Welcome to the ZDoom Forums!

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.

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:

tried the mod enjoyed it

this mod is great,but i guess the ramdomizer aspect is intentional no?i was gonna sugest to adda dificulty level selector that makes it so only a certain tier spawn.

Cool mod, having a good time with it.

This is absolutely a top tier monster randomizer. Been wanting more massive monster randomizers like these and some of them very in quality in the assets they use or have more boring monster design. This one really pumps up the difficulty and the monster variations actually feel very different from each other. The tier indicators are a REALLY nice touch, too! You did a really good job with this.

EDIT: 450+ monsters wtf!? I haven't even experienced like 10% of what this has to offer yet...
