Microsoft shows off first person shooters at Xbox Showcase Microsoft has been showing off some of its next generation first person shooters at the annual Xbox Spring Showcase. First up - the company's most popular series ever: the fourth installment of Halo. Not for sale until the 2012 holiday season in the US, Halo 4 aims to to satisfy longtime fans while pulling in new ones. Microsoft also showcased a game out this week - Mass Effect 3. "With Mass Effect 3, we've integrated the Kinect voice control," said Executive Producer Casey Hudson. That allows you to do things with the game that, normally you're screaming things at your TV to try and tell your squad members to do things, now they will actually respond. And for those who find the immersive experience of Halo and Mass Effect a bit too much, there is always Counter Strike: Global Offensive. "You know, a lot of the modern shooters, they have a lot of cool stuff in them, you know, I play them, I love them, there's a lot of things that like if you've played 100 hours you can have upgraded weapons versus the other guy," said writer Chet Faliszek.
