Appears to be identical to Serpentis Sanctum without the sensor dampening or blaster ships. Much easier on the tank due to cruise missiles hitting for garbage although you're REALLY going to want either a domi/ishtar or a separate DPS ship as you'll spend half your time jammed. Unlike in the Serpentis version, the next spawn only seems to trigger after you completely clear the previous one. There's a rings o' hardeners version, for more details, read the Blood Sanctum article.
For some reason, the version with the station starts with a 3xBS spawn ongrid, to trigger the rest of the spawns shoot the structure. Despawns really quickly if you have to warp out, I just leave my scout cloaked ongrid. Someone clean this up and put in a trip report, mine despawned when Comcast decided to disconnect all my clients randomly ;_;
Rats spawn when you attack the "pirate complex" large structure in the middle of the site.
Next wave spawns when any two ships remain.
Blew up station. Said "Dust and debris spews forth from the station as it quickly breaks apart". Nothing else.
Alternate Station Version
The first wave's four jamming cruisers are pretty tough to get past (did it with ECCM'd Typhoon, got almost perma-jammed, had good drone skills, survived only due to dual reps).
