Today Microsoft revealed the latest set of Games with Gold. Xbox One and Xbox 360 owners will have three more games to download for free in May.
For the entire month, Xbox One owners will be able to download CastleStorm: Definitive Edition for no charge. CastleStorm is a cross between a brawler and tower-defense game. Players defend their keep and try to destroy their enemy's by using ground troops, spells and artillery. They can enhance their forces over time using currency gained through battle. The modes include single-player, co-op and competitive multiplayer.
The Definitive Edition of CastleStorm also includes the two expansions, From Outcast to Savior and The Warrior Queen. Those DLC packs add a combined 40 battles to the game along with new weapons, characters and Achievements.
Through May Xbox One owners will also have the opportunity to download Pool Nation. Pool Nation, first introduced to Games with Gold in April, is a pool simulator that lets players watch and compete in live matches online. The game also includes a Trickshot Editor so you can build your own special moves.
Xbox 360 owners will have the opportunity to download Mafia 2 from May 1st to May 15th. Mafia 2 is an open-world crime game that takes place in the post-World War 2 era. The player is Vito Scaletta, an Italian immigrant who rises through the ranks of the Empire City underworld. The various unsavory tasks they'll need to perform will put both their driving and shooting skills to the test. The game's three DLC packs, which add new story-based missions, don't seem to be included with the freebie.
In the second half of the month, Xbox 360 gamers can download racing game F1 2013. The simulator is said to feature all the cars, drivers and tracks from the 2013 FIA Formula One World Championship. F1 2013 also included some racing content from the 1980s in case you're feeling nostalgic.
The three new games would normally cost you $85. You're not getting them entirely for free, though. You'll need to be an Xbox Live Gold subscriber to download them.
You've still got a couple days left to get April's Games with Gold if you haven't downloaded them yet. The April offering includes platformer Child of Light along with four Xbox 360 games. At this point you've missed out on Gears of War Judgment and Terraria for Xbox 360 but you've got a chance to download Assassin's Creed 4: Black Flag and Army of Two: Devil's Cartel for that console.
