The PC version of the beta of Tom Clancy’s The Division has been affected by cheating but the development team at Ubisoft is having none of it, as they mentioned on the official forums:
Over the last few days, we have seen an unprecedented level of interest for the Closed Beta. We are looking into your feedback with care and we are thrilled by your passion and enthusiasm!
We are aware of the cheating issues in the Closed Beta on PC. The team is fully committed to providing solutions against this and a system will be in place to ensure a fair experience for players when the game is released on March 8.
If you were worried about your future experience with The Division being ruined by widespread cheating, at the very least Ubisoft is on it. Hopefully, they’ll manage to remain one step ahead of those that can’t be bothered to play along with the rules.
