A-170 will spawn in the current room once the door has been opened. After 3 seconds it will spawn LOKR-170, 4 seconds later after LOKR-170 has spawned, it will spawn TBAL-170. The only way to survive this entity is to hide in the previous room. Never walk too far into the rooms when you open the door because if you get too close to A-170 when he spawns, he will kill you.
