The post apoc MMORPG Fallen Earth has recently started it's closed beta. For those that don't know what Fallen Earth is;
Fallen Earth is a massively multiplayer online game mixing
first-person shooter style action with traditional role-playing game
Set near the Grand Canyon in 2156 after a deadly plague wiped out
most of humanity, the game features six factions, a classless
advancement system and a unique crafting feature in which players can
make 95 percent of game items.
With 70 towns, real-time settings and interesting character
modifications—woven together in a post-Apocalyptic
plot—Fallen Earth provides ultimate player-versus-player
and player-versus-environment experiences.
To participate in their beta, you need to sign up for their forums/newsletter and apply. Seems to be a fairly casual MMO from what I've heard from people in the beta, so if you've got some spare time and interested, head on over to their site here
Alternativly, check out this video from a year or so ago to see what it kind of looks like instead of a press release.
Thanks to Soulie for the heads up
