My mind have words through me its " Tip: A-189 will be more difficult if you encountered Sta-278 (also known lunny), A-666 and NV-404. And Ma-278 is easier because she last short like 16 seconds after and before rebounding. The easier it is the more how to survive and the trickier it is is how run and encounted more entities in 1 A-189" and more "Tip: Theres a bug/glitch for A-189. When Xa-278 is near A-189 it brings or teleport them to A-345 or any rooms it teleport. The bug/glitch is called bring in, bring out".
