There's a trailer in the article that you can watch that pretty much just sets up the story.
W!Games is proud to officially announce Greed Corp, a fresh and innovative turn-based strategy game for PlayStation Network. It will be the first in a series of games situated in a rich, fictional world inspired by the industrial revolutions and their destructive effects on the environment.
Find the delicate balance between harvesting the land for resources and preserving it to stay alive. Will you defend your territory or sacrifice it to keep it out of enemy hands? Manage the finite available resources to build your army and use the collapsing terrain to your advantage. Destroy your enemies, or destroy the very land they stand on, before they do it to you.
The game features a comprehensive single player campaign, introducing you to the four factions that inhabit the world. A large collection of unique maps is available outside of the campaign, specifically designed for 2, 3, or 4-player battles. Matches can be played with any combination of local, online and AI players, allowing for quick access to multiplayer action and offering multiple unlockables for a variety of challenges.
Greed Corp will be available for PlayStation Network at the end of September 2009. Join the Greed Corp community and stay updated through http://www.greedcorp.com.
