I do enjoy this horde. My complaint is that the 4 advanced horde modifiers are locked. Not a fan of completing each level with the 3 ■■■■■■ starting modifiers on. This was a poor design decision IMO. I just want to choose which modifiers to use.
Another thing is this feels like Horde 3.0 with limited enemy types. Yes I know Horde 4.0 has more enemies. But how long before we get tired of seeing Leeches, Sires, Imago with Enforcers, etc. There are so many other enemy types TC could add into Horde. I would accept swarm drones with lancers or retro lancers a new enemy type. Seriously the more variety the better.
