Well, been awhile, figured I'd update this. As of now, it is in the beta phase
http://www.endofnations.com/en/beta/Anyway, the game has 3 factions, the Order of Nations which is the AI controlled faction and the 2 player controlled factions the Shadow Revolution and Liberation Front.
It will be another free-to-play mmo. It will have battles of up to 50 players each commanding 20 units.
As for the difference between the 2 playable factions, liberation front is more of your typical brawling faction with the big tough vehicles while the shadow revolution is a more cheap stealth based and speedy faction.
The irony of guns, is that they can save lives.
