Containment-Prison [∧]

- this npc can turn on the lights in the prison for 1000 AG & you can sell Disembodied Arm/Leg
- talk to the boss & select the „Hand over your Soul“ option
When you approach Prison you will receive a special radio message wich will tell you that you can now encounter Luci. This is a random event and the next fight after the announcement will be Luci.
- you need 2 brains to fight the prison boss
- Brain 1: kill the NPC in the Prison @[03,05]
- Brain 2: kill the NPC in the Poison Pit @[15,18]
Poison Pit [∧]

- kill the weakling @[15,18] and return his brain to the boss @Prison
There is another NPC @[15,20]. She is frightened and only mentions that you should spare the children. Yeah you just killed their dad and ripped his brain out of his body. Just leave them alone because you dont get any reward for killing them. Dont be so heartless…
After killing the boss in the Prison area you will receive a radio message that mentions a surprise @ your base.
So teleport back and kill the monsters in the admin tent & storage. The battles will be against occult race enemies so equip any captains blades you have found. And dont be too greedy – when you die its Game Over because the reactor is offline.
After clearing tent & storage there is a small event where you must make a decision. You can sacrifice the girl with the weelchair or yourself. Sacrificing the girl is easier because your party will take a lot of damage when you select the other option. And the next battle will be against 3 occult enemies…
Its up to you. I sacrificed the girl because she is immortal and there are no consequences.
Easy way:
- sacrifce the girl & kill the 3 guys
You have got balls of steel:
- sacrifice yourself and start the battle with 1 HP on most chars
- instantly activate Neuro Charge, spam mass heal and dont get killed
After the victory party visit the Cyborg @Pit level [06,27] and give him the old Bird Statue. You can now use the Stone Flowers @ the previous boss locations.
Go to the Prison @[13,15] and take the warp to Pilgrimage Cemetery because it is the easiest oft the 3 new dungeons.
