Everyone loves free stuff right? Free skins are especially great in videogames since most of them are all locked behind DLC or RNG loot boxes, so getting skins for free is always welcome.
To celebrate the 20th anniversary of Star Craft, anyone who logs into Overwatch within the next month will get a free "Kerrigan" skin for Widowmaker.
All you have to do is log into the game between now and April 3rd and the skin is yours. So log in, get that free skin, equip it, do badly, get bm'd and never play Widowmaker again. At least that's probably what it will be like for me.
