• They just spawn from convenient holes around the map, usually with a location trigger.
• They are damage-soaking thickboys.
• They have zero survival motivation, so they just run at me guns blazing.
• They are as fast as I am.
  • Throw a plasma grenade on them when they charge for that authentic Serious Sam experience.
• They can leap at me to close the distance, with a damn good melee attack too.
• They can shoot weapons, including turrets.
• They can drive and shoot from vehicles.
• The literal fleebags can revive the dead.

The only thing I think they don’t do is throw grenades!

Halo has some fun gunplay when facing off against humans or Covanent, especially managing my recharging shields against theirs adding a layer of necessary tactics. Even when I die I usually understand what I did wrong. With the Flood all that goes right out the window. A few Flood chasing you guns blazing is basically a repeating death sentence, only to respawn at some checkpoint five waves ago.

And boy don’t get me started on the lore logic required for all these Flood. It’s as if everybody in-universe makes the worst possible decisions that get everybody infected. There are so many questionable choices the Forerunners make for research that would cause Wayland-Yutani to raise an eyebrow. What is the point of the Halo Array if you are just going to send a time capsule of Flood to future species to accidentally Pandora’s Box?
