Respawn is discontinuing sales of the original Titanfall, but has told fans the series remains "core" to its DNA.
Titanfall launched seven years ago for Xbox One and Windows PC (before eventually heading to Xbox 360), and was primarily a multiplayer affair -- with the only single-player mode being a tutorial designed to show players the ropes.
In a post on Twitter, Respawn said it also intends to remove the title from subscription services on March 1, 2022, but will keep servers online for those who still own the game and want to drop into a match.
Respawn is currently focused on supporting free-to-play shooter Apex Legends, which takes place in the Titanfall universe, but there have been calls for the studio to revisit the series in full.
The last main entry in the franchise, Titanfall 2, launched in October 2016 and included a single-player campaign with a full-fledged narrative and some impressive level design (yes, we're looking at you "Effect and Cause").
Although Respawn remains fairly coy as to how the series will march forward, it has reassured players that "this incredible universe will continue."
