A datamine has confirmed Valve is moving Team Fortress 2 to Source 2.
Discovery Details
On 2025-12-01, Tyler McVicker, a notable Valve sleuth, revealed findings from a new datamine. The updates, taken from CS2 and Deadlock, included a branch labeled 'TF' with code directly related to Team Fortress 2.
- Source 1 import strings, added on 2023-10-14, are for porting TF2 elements.
- 'func_respawnroomvisualizer' is unique to Team Fortress 2 and confirms the transition.
Potential Outcomes
Though the datamine shows TF2's integration into Source 2, Valve's final plans remain unclear. Options include a remaster akin to CS2, a new sequel, or a tech demo. The project exists amidst ongoing development of Deadlock and no public announcements.
Despite uncertainties, this discovery fuels anticipation among fans.
