In lore we read that some labs were bombed to contain outbreak but all labs are untouched so maybe add new type of lab what enterance is rubble or have holes in walls and underground can have flooded rooms rooms on fire more netherworld creatures what are not in cages corridors blocked by big piles of rubble and most terminals are broken
Yeah. I mentioned it on another thread, but have some walls destroyed as well, so that if there’s still any turrets, you’ll have less cover to keep yourself safe.
In general, having more variety to labs will give it a better challenge, since once you know how to clear a lab, they become way too easy.
