J1M: Surface Protocol

The year is 2099, after decades of mistreatment, the planet has decayed to an uninhabitable sludge. It is your mission to reclaim the planet

QUICK PLAY IS RECOMMENDED UNLESS YOU ARE A HARD-CORE J:SP FAN

Gameplay:

Your goal is to purify the map using trees and water purifiers. As you progress, so will the environment around you.

Walkthrough:

Start by drilling a few crates or dead trees to gather biomass.

Once you have collected 10 units of biomass, you can build a sapling. After some time the sapling will grow into a tree which purifies nearby soil and grass.

Junk drops scrap which can be used to upgrade move/drill speed.

Once you have accumulated enough biomass, you can place purifiers on the toxic water.

Enjoy and try to purify the whole world!
