New Baby Cyber Demons with reduced health (equal to Barons). I like. They're just as deadly as normal Cybers but clean-up after the fight isn't as tedious. Normal Cybers are still a thing though, and they can even infight.
Cyberbros are helping.
Every map has a hidden pink keycard that opens a secret fight. These are always a bit more experimental.
Hate!
Bonus map by Insane_Gazebo (Sunder). It's like a collection of incoherent combat set pieces, most of them are cool, some are boring.
My favorite is this one with waves of crushers rolling through the arena.
Pro tip: Don't enter the secret fight without the BFG!
Too bad it ends with the most bog-standard circular hold-LMB-to-spam-BFG slaughter fest.
Map 06 starts with just 6 Revs and 1 AV, but somehow this is the hardest part of the entire map.
There is also an extra well hidden secret area which I'm not going to spoil.
