Riot Games Calls Its Unnamed MMO The Grail Just Months After Pulling the Plug on 2XKO

By CriticalPixel · 2026-09-07

Riot Games wants you to believe its mystery MMO is still alive and kicking, five years after the company first confirmed it was building one. Speaking at PAX West 2026, co-founder and chief product officer Marc Merrill dusted off the project's internal nickname, The Grail, and promised the team is chasing it with the same stubborn conviction that built League of Legends into a billion dollar franchise. The timing could not be worse. Riot just told fighting game fans that 2XKO, the free to play brawler it spent nearly a decade building, is losing active development in December because not enough people stuck around to play it. Merrill's pep talk landed right in the middle of that wound, and the gaming internet noticed immediately.

The Grail Quest Nobody's Seen

Riot first announced its League of Legends MMO back in August 2021, and five years later the project has cycled through leadership, including former World of Warcraft veteran Greg Street, who departed the studio in 2023. Development reportedly restarted from a more grounded position afterward, but Riot has stayed almost completely silent about specifics since. There is still no project name beyond the internal grail moniker, no release window beyond a vague promise of before 2030, no confirmed genre lean, and not a single screenshot or piece of concept art has leaked in five years. Merrill leaned into that mystery on stage, telling interviewer Greg Miller that the team knows what players want and just has to execute, joking internally that many a brave knight are going to die chasing the grail, but the studio is doing it anyway because the payoff is worth chasing. Riot Games later shared the exchange on its official account, teasing that this is what that MMO we are building looks like right now.

2XKO's Fall From Grace

The backdrop makes Merrill's confidence a tough sell. Riot revealed in an official blog post that 2XKO, its Arcane universe fighting game formerly known as Project L, ends development in December after the studio watched player retention slide for months. The game only fully launched in late 2025, and the final content patch lands in October before the servers settle into a lighter maintenance mode, with in-game purchases made before August 20 getting refunded and most cosmetics unlocked or discounted. Riot insists it is not walking away entirely, since online play and two new champions, Lux and Samira, are still on the way, but ending active development on a game barely a year old is the kind of decision that sticks in a community's memory. Merrill even addressed it directly at PAX, saying he would not call 2XKO a mistake and pointing to how brutal the free to play market has become, with tens of thousands of games competing for attention on Steam alone.

Community Reaction: Skepticism Runs Deep

Reaction across gaming social media landed somewhere between eye rolling and outright dread. Fighting game community members were especially blunt, with one widely shared reply arguing Riot is hyping up this MMO like it will not just get shot in the face after six months for not being bigger than World of Warcraft. Another user joked the MMO will launch alongside a Final Fantasy 14 expansion and get killed within three months for not making enough money, while a third asked why anyone should get excited for a new Riot game after how badly 2XKO got fumbled. Not every reply was hostile. A handful of League of Legends fans pointed out that Final Fantasy 14 also had a rocky multi year start before A Realm Reborn turned it into one of the genre's biggest success stories, arguing Riot deserves at least a little patience given its track record with League itself. Still, the dominant mood across the replies stayed closer to bracing for disappointment than genuine excitement, and that split says a lot about where trust in Riot's live service instincts currently sits.

The CriticalPixel Take

Riot picked a strange week to lean on vibes. An MMO with no name, no footage, and a five year old announcement is a tough pitch on its own, and pairing that pitch with a fresh reminder that the studio just cut bait on a fighting game barely a year into its life does nothing to build confidence. Live service games live or die on trust, and Riot spent a lot of goodwill telling 2XKO players it would nurture the fighting game community right up until the numbers said otherwise. Merrill is right that the market is brutal and that competing for attention against tens of thousands of Steam releases is genuinely hard. That does not change the optics of standing on a PAX stage and promising the grail is coming while thousands of 2XKO players are still waiting on refunds. If Riot wants people to believe in this MMO, the fastest way to do it is not another quote about mindset, it is a screenshot.

What Comes Next

For now, the MMO remains exactly what it has been since 2021, a promise with no shape. Riot has committed to keeping 2XKO's servers online and shipping Lux and Samira before development winds down, so fighting game fans get a slow goodbye rather than an abrupt one. Whether that softens the skepticism aimed at Riot's next big swing is another question entirely, and one the studio will only answer by actually showing the MMO instead of talking about it.
