Heroes & Generals

Heroes and Generals was actually Greenlit the previous time around, but since it was the only MMO at the time to be approved, I feel it warrants another look. Heroes & Generals is an upcoming MMOFPS by Reto-Moto. The game is an open world, free to play title set in World War 2, and mashes together first person shooter with real time strategy. Players on the ground take care of the assault while those higher up in command view the battlefield from a top down perspective and order strategic movements. Reto-Moto is made up of the original founders of IO Interactive, the minds behind the Hitman and Freedom Fighters games.
Heroes & Generals is currently in development and not set for release for some time. Players are able to sign up for a beta key at the main website.
Perpetuum

You likely already know about Perpetuum Online. Like a few of the other games on Greenlight, Perpetuum Online has already launched and has been available for quite some time. Sometimes referred to as Eve Online on the ground, Perpetuum is a single-server, sandbox MMO that focuses on players controlling highly customizable mechs in order to compete over the land, the resources, and the environment. Just like Eve Online, players are able to purchase and trade subscription items (PLEX) which would allow a player to play Perpetuum free of charge as long as they can make enough money.
Everything is manufactured by players, along with player-built settlements. The environment can be terraformed, and character progression is based on time rather than grind.
