Not sure if anyone waits for this game - it's a TF2-like game from Blizzard. Yes, those guys who did Diablo, Starcraft, Warcraft and a bunch of other games.
Anyways, game is closed beta now, some random people have access, and also many game journalists and game streamers got it too, so there are lots of streams available on Twitch if you wanna check it out.
But the good thing is that this weekend, from 20 to 23 of November, many more players that signed up for the beta in Battle.net will get access to Overwatch - Blizzard plans to test servers stability. This is more like an open beta weekend, and rumours are there will be many more of the before final release in Spring 2016.
Anyways.
If you like this kind of games - be sure to visit Battle.net Overwatch page and sign up for the beta - who knows, maybe you will be lucky to get access and play this very nice shooter.
