Factorio

Allows the biter/spitter spawn ratio to be modified.

This mod adds a nest of explosive aliens and worms! These aliens will explode on death (area damage) and spread fire. Fire spitters are also deadly burning everything! And if you see their Mother, run, run for you life! Say goodbye to your walls! Good luck!

A glowing enigmatic life form was found to inhabit alien forests at night. Based on the original mod by Betep3akata. Probably won't work in multiplayer.

Adds a few harder enemies.

Two game modes: PVP: Two teams fight a battle for their science robots. A mix o Wave defense and PVP scenarios, plus robots and jails. PVE: Defend your robots, and try to survive with your friends

Inventory items and grid equipment inside destroyed containers, like chests, vehicles (cars, tanks), will now spill over ground, instead of simply vanish. Adds a hotkey to pick items on ground with adjustable pickup radius. (Locale: English, Deutsch, 正體中文, 简体中文, Русский)
