In addition to the basic river valley that all players will start off with, you can also unlock regions such as a desolate island, a volcanic glacier, and a post-apocalyptic city left victim to flooding. Other maps offer more advanced tiers of machines, and you need to plan wisely to reach the required percentage of greenery. With proper strategizing, however, you can easily create more and eventually reclaim the land with verdant greenery, completing the level. This is because there are only three types of tiles available first: poisoned soil, dry riverbeds, and rocks-and you can only put turbines on rocks, which are few on the map. The other three tools are for unlocking more places to put a turbine on. You must place a turbine for electricity, a toxic scrubber to cleanse the surrounding wasteland, and a greenhouse to plant the greenery and earn back more currency. You earn currency by creating greenery using the six tools available. It's important to note that the chosen difficulty affects the building costs.
