There's a competitive element of Blizzard's Overwatch due to launch by the end of June. It's going to really change the way the game has played and give people a strong reasons to log in time and again.
Here's an overview of how the competitive play will work.
Exciting stuff, and it's coming to all players for free. This mode will allow people to really hone their skills and each success will bring its own rewards. That in itself is a minefield because Overwatch is a very finely balanced game so the developers have to make sure there's no advantage given to those players.
As such, the rewards for competitive mode will be totally cosmetic, ranging from icons and sprays to some extremely fancy looking weapons. Yes you'll actually get gold versions of your guns that will really stand out on the battlefield.
It's a great way to give a shout out to those especially skilled players which everyone can see without actually making them even more powerful - though you know if you come against a gold-carrying character they've probably got some serious skills.
An early look at these gold versions of the guns was found by Master Overwatch. Check a few out below and the rest through the link. Competitive mode will be available very soon.
