Civilization Revolution and Dungeon Defenders have been named as this month's Xbox Live Gold freebies, with the former available to download on Xbox 360 now.

Civilization Revolution will be available to download for free until March 15 and offers a decent console take on Sid Meier's classic Civ series, before co-op tower defence title Dungeon Defenders takes over on March 16.

The two games follow last month's freebies Dead Island and Toy Soldiers: Cold War.

It still isn't known when the initiative will make its way over to Xbox One.
