Overwatch 2 had a lot of issues at launch, some bugs that affect the games when players try to launch the title. Blizzard is actively working to resolve them by regularly releasing patches. In order to compensate for the DDOS attacks and the issues encountered by the players, the creators have decided to offer the Cursed Captain Reaper skin and the Health Pack Weapon Charm.
These free rewards can be claimed for a limited time which is from October 25 to December 4. So remember to connect to the game between its dates to receive them automatically.
