Crimson Gauntlet

Strategy

Room 1: Kill wave on warp in and head for the gate to your left, unless you have a key to take the short-cut (to Room 2) through the other gate.

Room 2: Kill all rats of spawn 1 and 2 while approaching the next gate. The gate activates after spawn 2 has been eliminated. (Sometimes a 3rd spawn happens?), make sure to be aligned for gate activation before you get tackled by the 3rd spawn.

Room 3: Deploy MTU, kill all rats of spawn 1 and 2, then the battleship NPC arrives. Kill that one and revealed structure for loot. Killing the structure may spawn an escalation for XXX (can spawn in HS/LS/NS)
Sometimes there's a 3rd wave spawning together with the battleship. You may need to kill the neuting and damage cruisers before killing the battleship to not die to the neuting/dmg pressure.

There have been reports of rifts spawning in room 1 & 2, which spawned sleepers. It's reasonable to assume there can be drone- and trig- enemies spawning too.
