Minecraft came out yesterday for the Xbox 360 and it seems it's going to be a huge success, especially for co-op gamers. One little problem for the game though, it's a pesky 1600 - that's $20 in real money. While that's still cheaper than the full version on the PC, that's a bit more than a lot of people are comfortable paying. Good news! You can get it for free today... here's how.
