If you didn’t have a chance to play some Overwatch (a Team Fortress 2 game on steroids, right?) you’ll have a chance to do that on February 16th. The free weekend ends on February 19th.
The free time will include full list of 26 heroes and 16 maps. Available game modes are: Quick Play, Custom Games, and the Arcade. You’ll be able to progress your characters as usual and keep them if you buy the game later on, which is pretty sweet because you can grab the game at any time and continue where you’ve left.
