Microsoft made a big deal of its new generous streak at E3, revealing Halo 3 and Assassin's Creed II would be given free to Xbox Live subscribers. It was hardly a drop in the ocean compared to PlayStation Plus, but Microsoft's really settled the score for July -- Defense Grid is free for all!
Please excuse me while I bow toward Redmond as if t'were Mecca itself.
The 2009 tower defense game follows Fable 3 in Microsoft's new Games With Gold scheme, planned to offer two freebies a month. PS Plus, at the time of writing, offers Deus Ex: Human Revolution, Uncharted 3, Saint's Row: The Third, XCOM: Enemy Unknown, LittleBigPlanet Karting, and more for free, plus several discounted games.
On the bright side, you also get loads of advertisements with your Xbox Live gold subscription, so don't say Microsoft never does anything for you. Sorry, did I say for you? I meant at you.
