It doesn't exist.Team Fortress 2 (2007) launched on PC (Steam), later Mac/Linux. The Xbox 360 version was cancelled in 2009 due to:
Valve's dissatisfaction with Microsoft's patch certification delays & fees.
Inability to deliver frequent updates (TF2's core model).
Memory constraints (512 MB) vs. growing PC content.
