Just wanted to mention the Siege Game mode that been steadily growing for a good while now.
Its basically a mixture of FPS and an RTS game, where you have to 'build' up your base defences and earn Resources (money) to buy Redeemers to kill the enemys core.
Sounds complicated, but after playing it a couple of times you'll be having lots of fun! =)
The official site is www.siegexxl.com Where you can find lots of information and downloads on the game mode.
There are a few good public servers hosted mainly by nOs* siege clan and |uK| siege clan:
