During the BlackBerry DevCon general session keynote, Alex Caccia of Marmalade took some time to show off a bit of what the BlackBerry PlayBook can do. It seemed that much of the keynote was about gaming on the PlayBook and here we got a good look at the upcoming Lara Croft and the Guardian of Light. I for one and super pumped to check this game out in full as I've been a big Tomb Raider fan for years. The gameplay looks amazing and I'm hoping it will be a hit. Check out the video above for more.
