So, Green Planet is out along with a free update.
The free update includes:
1. Landscaping! You can now level terrain, remove those fuckoff-huge rock outcrops in the way of your ideal dome location, and make massive ramps to span the height differences between Martian plateaus. Can also change the surface texture. Just a visual thing but you can finally get rid of the old rocket scorch marks or make the area outside your dome look nice and uniform. Drones can do landscaping or you can use the new rover, the RC dozer, to do landscaping projects far from your drone hubs. Landscaping requires waste rock when you are filling holes or raising terrain, and gives you waste rock if you are lowering terrain. Dozers on automatic once you have the rover AI will drive themselves to any landscaping project to help and will deliver or haul away waste rock. Example:

2. New special projects, such as launching high speed comms sats and redirecting meteors toward your colony's map to maybe get extra metals/polymers and also maybe accidentally hit your colony!
3. 2 new "buildings". One is a 'rocket construction site' where you can build your own rockets (once you have researched the tech). The other is a larger waste rock dump site. Waste rock is now used in landscaping and terraforming, and can be moved around by rovers.
4. 20 new events to add some content to the mid/late game.
5. Reworked tech tree screen. It's a lot better.
6. Lots of optimization. Even late game now the game runs well on my computer. It used to start to chug around 3-4 hundred colonists
7. It's not mentioned much but you can also now shift-click to queue rover orders, and click-drag to band select drones and rovers and such.
Green Planet
Well the big thing here is Terraforming. You can terraform Mars! This works by influencing 4 statistics, Atmosphere, Temperature, Hydration and Vegetation. Each of these goes from 0% (martian normal) to 100% (earth normal). You influence these in various ways, either by using buildings to pump out greenhouse gas to raise the temperature or by sending rockets out to redirect water-ice asteroids to Mars to raise the hydration. Eventually you can, with enough work, make the skies blue and the ground green. I especially like planting forests around my domes and now I grow all my food in open farms outside.
And speaking of domes, once your terraforming gets far enough along you can open your previously domed cities and even build a 'capital city' which is totally open and HUGE.
It's been a lot of fun so far. The endgame used to kind of drop off once you finished the mystery and all of your sponsor goals. Now you have another, larger goal. Make that red planet green.
