Which is why I compared it to Doom. You read my post incorrectly.
After first-person shooters made the jump to fully polygonal 3D, monster swarms disappeared - probably for performance and pacing reasons. Halo (and Serious Sam) brought them back, which is something that most people forget. Halo's single player combat was much larger in scale than the Quake-style corridor shooters that dominated the market in the late '90s.
