The roster design that stops combat from becoming the same solved problem in a different room.
Enemy variety is not about stuffing a game with dozens of models. It is about creating enemies that ask different questions. One enemy pressures distance, another punishes blocking, another buffs allies, another forces vertical movement. Variety matters most in combinations, where a simple enemy becomes dangerous because of who stands beside it. The goal is a combat vocabulary players keep reading, not a bestiary that only changes visually.
Example
Doom Eternal's roster is brutally functional: Cacodemons demand grenade shots, Arachnotrons lose their turret, Marauders force timing discipline, and fodder enemies become resource pickups through glory kills and chainsaws. Halo's Covenant works for the same reason, mixing Grunts, Elites, Jackals, Hunters, and vehicles into encounter puzzles rather than raw firefights.
Why it matters
Enemy variety is how designers extend a combat system without constantly adding player abilities. A thin roster makes even great mechanics stale, while a strong roster turns familiar verbs into fresh situations for hours.
