mo.co: Supercell's Invite-Only Experiment, Its Reboots and Why It Refuses to Die
It launched in 2025 with a velvet rope, opened to everyone, went back into beta and was rebooted with seasons. Supercell admits it is underperforming but says killing it is unlikely. A rare look inside a struggling launch.
Supercell has a famous habit. When a game does not reach the bar, the Helsinki studio kills it, often before most people ever play it. So the story of mo.co is unusual. It launched, stumbled, opened up, went back into beta, was rebooted, and in August 2026 Supercell said publicly that it is "not performing as well as we hoped". And yet, by the company's own account, shutting it down is "an unlikely scenario."
A launch with a velvet rope
mo.co launched in March 2025 as Supercell's seventh global game, with a catch: you needed an invite to play, either from a content creator or from Supercell itself. It is a monster-hunting action game with a cheeky premise. You work for a slightly suspicious start-up that sends hunters into rifts to clear out monsters, and you team up with friends to do it.
The invite system created buzz. In its first week, the game reached about 2.5 million downloads and around $570,000 in player spending, according to estimates. That is small by Supercell standards, but the studio said it wanted to build a community slowly. In July 2025, the invite requirement was dropped and the game became available to everyone worldwide.
Back into beta, then a reboot
Opening the doors did not turn mo.co into a hit. The game went back into beta, an unusual step for a title already on global stores, while the team reworked its systems. The reboot went live in May 2026, adding seasons and free gacha pulls, a random-reward system where players earn draws through play.
About three months later, Supercell gave a frank update. New weapons and gameplay changes looked promising, it said, but the core loop "quickly gets stale for most of our players." At the same time, players who stay play for an "unusually high" amount of time. In other words, mo.co works well for a small, devoted audience, but is not ready to grow. More changes are coming and will disrupt the next season and probably the one after.
Why it struggled
Supercell's own explanation is about repetition: once players learn the hunts, there is not enough variety to keep most of them coming back. The monetisation also stayed light, which is kind to players but makes it hard to fund a large team.
The context does not help. Squad Busters, the studio's previous new game, was shut down a little over a year after its launch, and mo.co's revenue sits far below even that game. Meanwhile Supercell's older games, especially Clash Royale, were enjoying huge revivals, which made the gap with the newcomer even more visible.
Why Supercell keeps it alive
Supercell says a game still searching for its place "is always at risk of being discontinued", but closing mo.co is not in its plans. The reason is that devoted core. High playtime among the players who stay suggests there is something worth finding.
WGC's take
mo.co is a rare, honest look at how hard it is to launch a new mobile game, even for one of the most successful studios in history. Most companies would quietly shut a title earning this little. Supercell is instead treating it like a long-running experiment and telling players what is going wrong. Whether it becomes a late bloomer like Brawl Stars or a lesson learned, it is one of the most interesting stories in mobile right now.
