Even if you’ve already saved the galaxy in Bioware’s epic sci-fi adventure Mass Effect 3, you’re likely still slaying baddies in the game’s addictive online co-op mode. Fortunately for those who enjoy taking down Reapers with friends, Bioware is offering a completely free “Resurgence Pack” add-on for the game on April 10th. The expansion pack adds new playable characters to the mix, such as Batarians and Geth, two new maps inspired by the single-player game, and a handful of new weapons. This is fantastic news, considering most developers charge money for similar content, Bioware included. Grab your friends and get back to the fight!
