During its League of Legends 10 year anniversary stream, Riot Games teased several new projects including one that we got almost no information on.

The game was only shown for a few seconds on stream, but it seems to be something along the lines of an multiplayer dungeon crawler that involved clicking to move your character around. Riot described the game as “a project that explores the possibilities of traversing the world of Runeterra with your friends” in an email to Polygon.

Aside from the brief screenshots on the stream, Riot also called the game Project F, which fits in with naming scheme it has used for newly revealed projects recently. The tactical shooter, which was also announced on stream, was called Project A, and the fighting game, which Riot announced but couldn’t show much of yet, was called Project L.

As part of the League of Legends 10 year anniversary stream Riot also announced pre-season changes for League of Legends as well as a mobile version of the game. The stream also revealed that set 2 of Teamfight Tactics is coming, complete with 50 new units, and a mobile version of the auto-battler will be arriving sometime next year.
