Work in progress. Aliens now have nasty infestation (base-game tiles with a purple tint) that destroys everything in its path. Only water and player-made hard surfaces (bricks/concrete) can stop its spread.
when i look at the mod i have to think of creeperworld 4. now only an infested launcher and an infested spawner are missing.
biters = blobs spitter = skimmer
time to try out the mod ☺
