Free-to-play MMO Fallen Earth has come to Steam, according to publisher Gamersfirst.

The game can be downloaded via the Steam client while purchases can be made using Steam Wallet.

However, users who purchased the game either in retail or through its original release on Steam will receive three days of commander Premium along with the Hermit Crab pet, Trashy.

Achievements earned through Steam previously will also be synced in the next few days.

Fallen Earth is a post-apocalyptic MMO that combines FPS and RPG styles. The game was initially launched in 2009 and adopted its F2P model in late 2011.
