A few Redditors appeared to have datamined Fire Emblem Heroes (again) and came back with a trove of potential new info, including details for a possible summer event titled "Ylissean Summer".
According to Reddit, a future update will unlock the summer event, which will include new variant versions of existing characters-in this case swimsuit wearing version of Robin, Tiki, Gaius, and Frederick.
The datamined assets also include new beach-themed stages Reddit says are for the new Paralogue missions. These stages are complete with the ocean and some tropical looking palm trees which definitely feel "summer-y".
You can see a full list of uncovered materials over at Reddit, but the main takeaway from this whole thing is that we're going to get some heroes in swimsuits. Like bridal dresses and bunny outfits before it, new costumes are quickly becoming the bread and butter of Fire Emblem Heroes, you know, aside from the strategy gameplay and everything.
