So i killed KILLA 50 times. It goes like this
- Spawn
- Wait till 39:38 to check if there is KILLA
- If KILLA is there I use SJ6
- Rush 2nd floor
- Flash, Flash, Flash
- He says 1 out of 2. "HA-HA OOBEGAYU OOBEGAYU" "UGH BLYA"
- BS, BT, PS, SNB bullet in the head (top of the head)
- Extract with no backpack
Here are MOST (maybe even all) of KILLAs spawns (marked with red dots)
HUGE tip, if you see KILLA next to a door, hit him once, or make him aggro. Close the door and wait him. He will clip through the door and teleport back. This way you have ~1 second of opportunity to shoot
