Extremely fun zombie survival game. It's British, it rewards strategic planning over where to make your stand, and allows large amounts of explosives to be brought to bear on the horde. And the classes make it more rewarding to play as a team.

Has a steep learning curve to learn how the global world map works and how to effectively manage your resources and troops, but a large variety of weapons and equipment, decent (though sometimes stupid) AI, a large open world to play around in make this a solid game. If you liked Warband, but wanted guns, this is for you.
