If you are looking to add to your Xbox collection both for Xbox One and Xbox 360, look no further than Microsoft's massive sale on Xbox games. Major Nelson posted today on his website the sale, which includes some of the very best for Co-Op including Gears of War 4, Rayman Legends, Borderlands the Handsome Collection and many more. If playing games without friends is something you are more interested in, the sale has you covered, including multiple Assassin's Creed titles, I am Bread, Far Cry 4 and many more.
The original post and the entire sale can be found here.
This sale is set to last until March 20th, but that is enough time to play through one game and then maybe buy another. Many of the games in the sale carry critical acclaim, so making sure they are in your collection at this price is simply a sound investment.
As always, for coverage of sales, Co-Op and games altogether, stay here with your friends, at Co-Optimus.
