Happy Game and Dead Island 2 are the Epic Games Store's free mystery games for May 2025. This is the first time that either of these titles is being given away to Epic Games Store users.
The Epic Games Store's freebies are typically announced one week in advance. Occasionally, however, the platform runs mystery game promotions, withholding the contents of upcoming giveaways until they are made available for download. This approach was most recently used on May 8, when Epic revealed that the following week’s offerings would consist of two mystery titles.

In terms of what's on offer this week, Dead Island 2 needs no special introduction, being one of the most popular and longest-lasting co-op games in recent history. After surpassing 1 million sales within three days of its April 2023 release—marking the biggest launch in the history of its publisher, Deep Silver—the brutal first-person action RPG went on to sell over 4 million units, according to the latest figures reported in February 2025. Dead Island 2 currently holds "Mostly Positive" reviews on Steam, based on over 9,000 user impressions. It also has a "Strong" rating on OpenCritic, with an average score of 75, placing it in the 60th percentile of all games scored on the aggregator platform.
While Dead Island 2 may be a brutal zombie murder simulator, the title of this week's most terrifying EGS freebie goes to Happy Game. Even though its name suggests otherwise, Happy Game is an absolutely horrifying experience about a little boy who falls asleep and ends up in a deeply unsettling nightmare from which he can't wake up. Its psychedelic visuals and themed puzzles resonated with players and critics alike, as reflected in its "Very Positive" Steam reviews and 74 average score on OpenCritic.
