An online world where players must build civilization using resources from an ecosystem that can be damaged and destroyed.
Here's their announcement about it on their website to find out more about the game: http://www.strangeloopgames.com/announcing-a-new-world/
I'll give a brief summary below:
In Eco, you play on a world with many other people, on a world where a disaster will take place in 30 days! (So far, I believe they have planned a giant meteor and floods.) You and your friends have to work together to progress in technology to stop the disaster from destroying the world, while at the same time trying to keep the ecosystem intact. It's a balance of ecology and economy as you use teamwork to save the world from a meteor - and from itself!
The game is currently in early development, and will soon be in alpha. They had a kickstarter campaign for the game, and though it's now over, you can buy access to the alpha and beta version (for up to 4 people!) until the alpha comes out, which could be pretty soon!

I think it sounds like fun, and if I can afford the money, I'm going to buy the game. If any other Squishies out there pick up a copy of the game, let me know!
