Null Sec, Cosmic Signature, Level II or III, Combat (Drones). I think the level II and level III are slightly different.
Easily completed.
Escalates to expedition: Trouble in Paradise (Level 5 difficulty)
NOTE In second room, must approach Warning Sign in second room to trigger additional waves
The warpin has nothing but an acceleration gate.
The inital acceleration gate dropped me 2,200m from a beacon, so I maintained my cloak going in. I got in position and started sniping.
Unstable wormhole and ripped superstructure with ruined monument are main objects in first room.
Initial defenders (on the run that gave escalation)
On another run I got 3 cruiser and 2 bc (level II scan sig)
Easy quick kill of initial wave.
A wave spawns when you hit the acceleration gate, locking the gate:
On the run I got escalation (level iii):
On another run (level II sig) I received 3 BC and 4 Cruiser, no frigates)
I could not attack or destroy any structures in room 1.
Warpin decloaked me on the beacon, and sentry towers attacked immediately. I burned out to distance and started sniping. The towers don't hit past 120km or so, but hit hard inside that. On second run, was able to cloak and get to position.
Waiting in room 2:
After initial defenders are clear, more enemies won't spawn until warning sign is approached. I killed the Heirarchy building first (maybe this helps trigger escalation?)
Notable structures
There is a Warning Sign object. Trying to approach. Triggered a wave at about 35km distance.

Then
On one run I got 2 supremes.
Then after everything dead
Battleships start hitting around 80km. Tankable even at 50km. But on another run, the Alvus queens wrecked me and I had to warp out.
I got the escalation after killing the Supreme BS, before the final wave spawned with the Sentient.
