Overwatch released a relatively short time ago, and already it has become one of the most popular and celebrated games out there. If you ever wanted to figure out why this is the case, you'll be glad to hear that you'll soon have a chance as there is a free weekend on the horizon.
The free-to-play period will last from November 18 to November 21, and give you access to all 22 currently available heroes, all 13 maps, as well as all of the game modes and rewards that come along with them. What I'm trying to say with this is that you will have access to the entire game, no pointlessly locked away content or any such nonsense, just you and a couple of days of shooty fun!
Personally? I would recommend you give it a try because Overwatch really is something special. Ever since the glory days of Team Fortress 2 I have not played a game that has gripped me in such a way. I've started playing Overwatch back in the open beta, and I have continued playing it to this very day! But most importantly of all, I feel that my appreciation for Overwatch has only grown with time as the developers have done everything in their power to keep it as entertaining and balanced as possible. So give it a try, you might just find something more than a simple FPS!
On a somewhat unrelated note, Blizzard recently announced a brand new character - Sombra. If you would like to check out her animated short, as well as a brief overview of her abilities, I'd suggest you head over here. Unfortunately, she won't be a part of this free period as she's still undergoing testing on the PTR (Public Test Realm), but its always nice to know that there's more content coming in the near future!
