Insomniac has released a new developer diary for Resistance 3, which features the first gameplay footage of Capeill smashing Grims with a giant Sledgehammer. It also provides a detailed look at the human guns in the game such as the Magnum, Carbine, and Marksman, as well as a look at the upgrades attainable. Check the video out below. Also, Gamersyde has some screens up for the game. They aren’t the same ones posted here, and a couple look familiar, but have look anyway just in case. Game’s out next month.
