During a match of Overwatch, Philip "ChipSa" Graham accidentally found a random Doomfist bug/exploit. It doesn't seem to be one that can take over games, but he was able to use it effectively.
It's common to see random glitches in Overwatch even in professional matches. This doesn't seem the same situation though. After ChipSa ulted, he landed on top of the moving platform, but morphed through it and appeared under it. He couldn't move or shoot out of the space until the platform hit the floor. He must have been invisible as both Zentayya and McCree were completely oblivious with to him.
This isn't the only new thing we've learned lately about Volskaya Industries. It's full of surprises!
