The official Brawlhalla Instagram account posted that the Shrek crossover event has begun. The post was published roughly five hours before this article.
According to the announcement, players can now access Grand Tournament crossover content. The post names Shrek, Fiona, and Puss in Boots as crossover additions. It also lists a Donkey Companion, new Swamp Maps, and additional crossover content as part of the event.
The community reaction on the post was immediate. Comments included praise for Fiona’s visual design, comparisons between the crossover art and DreamWorks character work, excitement that the crossover arrived before a fifth Shrek film, and crossover legend design discussion around Puss in Boots and Fiona.
No official end date for the crossover event has been announced in the post. This article stays strictly to post-visible facts and does not speculate beyond what the caption or top comments here confirm.
