I'm thinking elite eweb and elite trando.

Mak has been tearing my guys up now that he has three activations and a Tier three gun.

I'm plannin to use the nexu to block the first door and hinder movement.

What did everyo else do?

I run subervise tactics

For the Source?

You just keep spawning Nexu and Royal Guards and keep them Stunned and Bleeding. They'll be too busy clearing conditions to notice that they are in Round 4 and still aren't out of the first room.
