How big? 3x3 is fine, a full density 5x5 could happen rarely, anything more than is weird.[/quote]
I avoid fungaloids like the plague… until I have a fusion rifle, and then I go slaughter them all! HAHAHAHAHAHAHAhahhahahaahahaaaa…
Oh, erm, excuse me. Anyway, with that particular setup, instant fungal terrain doesn’t really change things much. Trying not to evil laugh again…

Edit: ew, what about underwater fungaloids? That’s already a MASSIVE pain the rear to deal with. Having underwater fungal terrain (that you can’t see or burn, but continues to spit out spores) would be INSANE.
