End of Nations is an MMORTS brought to you by Trion Worlds and Petroglyph Games. It’s set in a persistant world of combat where teams fight out in battles of 2-56 players to decide on territory. Players win exp and may customize and develop their armies on the way to global conquest. The game is due for full release sometime 2012.
