All Prometheans are annoying as hell!
The Knights are pretty much the definition of “You’re going to die”. Powerful shields, one hit melee kills, teleportation that regenerates their shield instantly, and they spawn Watchers.
Watchers are just as annoying. They just a kill blocker when it comes to enemies. And when you start shooting them, they just run away for cover. And when you go back to shooting the main enemy, the Watcher comes back and blocks the kill again.
Crawlers are relentless and honestly don’t care if they die. They simply keep swarming you until you’re dead. You cannot run, you cannot hide. Because they’re everywhere. The ground, the wall, the ceiling, everywhere. Can it possibly get worse? Crawlers Snipers…
They’re all frustrating. But you know what? At least they’re not the Flood.
