Games firm Blizzard is apparently preparing to reveal a sequel to team shooter Overwatch at this year's Blizzcon.

That's according to ESPN, which cites a source from the upcoming event as well as a training document for the convention. Overwatch 2 will apparently feature a PvE mode as well as one mission which is a four-player level compared to the six-vs-six gameplay Overwatch is known for.

There's also a new mode on the way, too, called Push, which will join Assault, Control, Escort and Hybrid. It will use a new map called Toronto.

Blizzard does need a win at this year's Blizzcon. The firm has managed to alienate much of it community, in addition to members of its staff, over its decision to ban Hearthstone professional player Chung "Blitzchung" Ng Wai over his pro-Hong Kong stance during a post-tournament interview. This also drew the ire of a bipartisan group of US politicians, who wrote to Activision Blizzard boss Robert Kotick. Blizzard defended the action saying that it had nothing to do with the company's ties to China. 

Pre-event hype for unannounced games was also one reason that fans were annoyed at Blizzard following last year's Blizzcon. Members of the community were expecting a brand new PC Diablo game, only for the company to reveal mobile title Diablo Immortal. That went down about as well as can be expected.
