Weekly Brawls will change from week-to-week, with Blizzard promising some “surreal twists” and “custom rulesets” along with weekly rewards.

'Hammer Time' is one of the brawls that's been revealed so far. As the name suggests, everyone plays as Sgt. Hammers, but with thrusters permanently engaged.

Some Brawls will take place in a new arena, Lost Cavern, where players will fight over a single lane. There are two more new arenas that are to be announced, as well as some gameplay modifiers.
