On the cusp of a new month, Microsoft has already unveiled their free games for September in the Games with Gold promotion. Don’t forget to get the latter August games (Dead Rising 2 and Dead Rising 2: Case Zero) before midnight!

First up for August we get Magic 2013 ($9.99). The game is based on Magic: The Gathering card game and focuses on Duels of the Planeswalkers. It offers up some paid DLC (not sure if that will be free yet) and some complimentary downloads too. Also, the game has 2 player offline coop and up to 4 player online battles with your deck. Fans of the franchise shouldn’t be disappointed.

Get Magic 2013 (Sept 1 – 15) – Face a greater challenge in the latest version of this hit franchise. Play with friends or the AI, take on new encounters and opponents, and face up to three other players in the Planechase multiplayer format. Featuring ten customizable decks, Magic 2013 offers new game items to unlock and introduces the option to choose what lands to tap when you cast your spells.

The second half of the month offers up something drastically different in Tom Clancy’s Rainbow Six Vegas ($19.99). The game offers up a first person, tactical shooter. Fans of the series have probably played it already, but FREE things are pretty awesome. There are also some Player’s Packs that include new maps, modes, and more for free as well.

Get RainbowSix Vegas (Sept 16-30) – Rainbow operatives take to the chaotic streets of Las Vegas as an escalating terrorist siege in “Sin City” threatens to take world terrorism to new, uncontrollable heights. The future of global security hangs in the balance as you battle to defend classic Vegas locations and environments like Fremont Street, the Strip, and casinos.
