Welcome to Reactonix!
A wealth of tools. Materials, living creatures, forces of nature and much, much more are in your hands. What happens to the world is up to you.
P.S. Most importantly, don't try at home what you do in the game! (=
Forces of destruction. After all, who doesn't need a little fire for fun now and then?
Life — from familiar to alien. From ordinary plants to unimaginable beings and an evolutionary life system that depends on environmental conditions.
Physical processes. Detailed simulation of natural phenomena, down to the ability to control individual cells.
Co-op. Invite friends into your world or join theirs to create and destroy together! Or maybe, not entirely together... (=
Workshop. Share your worlds and recorded statistics with the community!
Mod support. The game includes tools for integrating mods into many parts. Create new tools, materials, processes—or something bigger—if you want!
Multiple view modes. Is it boring to look at the world with only your eyes? Observe temperature, creatures and other processes separately!
Statistics. Ever wanted to feel like a scientist? Now you can rely not only on your eyes but also on numbers and charts!
And remember, EVERYTHING here is under your control! (Unless your friends get in the way. (= )
