I've been thinking a lot about how to help make the community grow. I think its up to the people who love this game to make it happen much more than EA's and Crytek's marketing campaigns. I've noticed WarSpirit supporting the game by making positive comments on people's Youtube channels who upload clips of the game. So I've followed suit. I've set a beacon on my Xbox account that I'm looking for players to play Crysis 3. A couple of people have enquired. If you have any ideas I would love to hear them.
