Split Fiction has earned three Guinness World Records
In an announcement no one was expecting today, Guinness World Records has shared that co-op hit Split Fiction has earned three world records.

According to a post from Guinness, Split Fiction has set three world records. The co-op action-adventure game took the world by storm earlier this month, quickly becoming 2025’s highest reviewed video game according to both Metacritic and OpenCritic. This follow up to Game of the Year winner It Takes Two looks poised to at least be in the running for the award again this year. In our review, we called Split Fiction “another jewel in Hazelight Studio’s ever-growing crown of co-op adventures.”

Split Fiction was already known for great reviews and a high player count, but, as everyone knows, it’s not an official world record until it’s confirmed by Guinness World Records. Thankfully, today, in a post to their website, Guinness World Records confirmed that Split Fiction has set several records. All three of the records revolve around the perfect categories for Split Fiction to crush the competition: local co-op. From Guinness: “Split Fiction has become the most played local co-op videogame on Steam, most sold local co-op videogame within 48 hours of release and most sold local co-op videogame within one week of release.”
So, yes, these world records are fairly specific, but that doesn’t make them any less impressive. Split Fiction sold over a million copies within 48 hours of its release, earning itself one of the world records, and continued to sell another million over the first week to earn another. Split Fiction’s player count hit 259 thousand shortly after its release, which ranks it at 52 in the list of highest concurrent Steam player counts of all time, according to SteamDB. Considering most other games at the top of this list are massively multiplayer in comparison, that’s a very notable achievement.
Split Fiction is a local co-op game, but a large part of its success is the impressive integration of the Friend’s Pass. This feature allows two players to play the game online even if only one player owns the game. The Friend’s Pass was a feature with It Takes Two as well, but Split Fiction was the first game to introduce cross-platform play, meaning that the two players did not have to be playing on the same platform.
Hazelight’s director Josef Fares, replied to the announcement on social media, saying: “Wow, this is a fun surprise…” showing that even the game’s director didn’t expect this news today.
