Just as a precursor I am not posting the pack's download until I reach alpha! Right now, it is so underdone that I don't want it released yet!
Anyway, I need ideas from the Alien Isolation video game that could fit into Minecraft add-ons! so far I have the xenomorph being the Enderman with a new texture and EXTREME damage, but that's it. Blocks? Items? MORE ENTITIES? I need ideas, people!
