Some crafty Overwatch players have discovered a bug where you can use Mei's ice wall at a certain position in the spawn room of Ecopoint: Antarctica to escape the spawn room and attack the enemy team without getting attacked back, however, they won't be able to do this for long, as Blizzard have identified it and are working to fix it.
Principal Level Designer Dave Adams acknowledged the bug on the forums, and Game Director Jeff Kaplan posted an extended update on the blog on another post:
"This bug was surprisingly tricky for us to track down but we believe we have identified a fix. Our hope is to have it fixed sometime tomorrow (1/5/2017 PST) but there is always the chance that our fix could fail. We're currently testing to verify the fix."
"This bug is clearly an exploit and we consider this cheating. Do not attempt to reproduce this bug. If you see someone abusing this mechanic, please report them. We will be taking action against those who abused this exploit. Overwatch is a PvP experience so that means exploiting game mechanics like this comes at a cost to those you are competing against. We take aggressive action against people who abuse game mechanics, hack or cheat. This case is no different."
"Apologies that this bug lingered for as long as it did. Hopefully this should go away soon (along with those who abused it)."
Strong words of condemnation from Kaplan. Do you consider this cheating?
