If the alpha didn't exist I would've pre-ordered already. It really put me off.
Same 3 guys to kill and no loot. We're expected to grind, fighting a boss for 20 minutes? And then to a lesser extent there's the obvious monster closet and poor voice acting. I don't know or care about whoever the fuck Peter Dingleberry is.
It's been a while now, but I remember there's the flying thing, the normal guy and the one that runs at you.
Just off the top of my head:
Fallen Shanks (flying robot)
Fallen Dregs (two-armed dudes)
Fallen Vandals (four-armed dudes with special weapons)
Fallen Captains (big four-armed dudes with heavy weapons)
Fallen Walker (six-legged tank boss)
Servitors (a tiny death star)
Sepiks Prime (a big tiny death star boss)
Hive Thrall (zombie chargers)
Hive Acolyte (needler guys in cover)
Hive Knight (muscle zombies with swords)
Cursed Thrall (straight-jaket zombies that explode when you kill them)
Hive Wizard (floating dude that throws poison energy balls)
Did you just watch someone stream the Alpha for like 20 minutes?
