TerraGenesis - Explore Space and Terraform Planets

By Alexander Winn

Open iTunes to buy and download apps.


Engage in space exploration and terraform new worlds in this fun and exciting planet building simulator that’s rooted in real science. The universe is your playground in TerraGenesis!

The wait for the biggest update in TerraGenesis' history is finally over - now you can create custom organisms and allow them to interact and build their own global ecosystem with the new Biospheres. Change your world’s atmospheric pressure, oxygen amount, sea level and more in pursuit of terraforming an entire world to sustain life in your newly generated Biosphere.

TerraGenesis dynamically animates entire planets with changing biospheres, all based on real data from NASA. Explore the surface of the all new Dwarf Planets, colonize alien worlds, and spread life across the universe in epic games with Biospheres finally available for you to grow your own civilizations.

TerraGenesis Features:

- Start exploring the furthest reaches of space and inhabit one of six all new dwarf planets to build your terraforming colony
- Explore the frigid Boreas. Melt the ice caps to create planet-wide oceans and seed the planet with life (free for players who bought all of the previous planets)
- Build Satellite Colonies on moons orbiting your planet and conduct engineering projects from space for powerful terraforming bonuses
- Track your civilization’s progress and view your world’s current status with the Stats Summary Page
- Transfer Genesis points from world to world, with no game-specific limitations

- Finally, you can now build your own functioning ecosystem with interacting, custom organisms
- Start with 26 different phylums and add 64 unique genes to create all kinds of amazing organisms to inhabit your world
- Watch your lifeforms thrive in both terrestrial and aquatic biospheres and experience 12 completely new and random events

- Generate random worlds with complete surface and elevation maps, unique starting conditions and more

- Colonize real planets from our solar system, including Mars, Venus, Mercury and Earth

Just some ideas

Ok so I love this game and it has a lot of potential but what I would love to see is if you could go and land on the surface of the planet and look around if that's at all possible then please do it it'd be an awesome addition to an awesome game

Best app game I've played in awhile..

Paying for every other planet is a little much but the game itself is beautiful and fun.


I *love* this game! I screwed up my first playthrough, drowned my main colony, so I started over and it's going much better this time. I can definitely see myself buying a few planets once I finish with the free ones.


And now I've been playing for a month or so and am still totally addicted. I will probably buy all the planets eventually, but I have to say that the random planet generator was *really* worth getting.


Even more love now that they've added biospheres. They're a lot of fun to tinker with.
