Pick a TF2 merc; chase a stock-kit challenge in your Dota match.
Pick one of Team Fortress 2's nine mercenaries and pursue their kill or assist contract while playing a real Dota 2 match. A companion panel reads your current Dota hero and match stats from Dota's local Game State Integration feed. It verifies the matching mercenary and stock-weapon model paths against the VPK index in your own TF2 installation, and shows those verified model paths alongside your challenge.
Dota 2 stays the primary game and is left unmodified; the standard local GSI configuration is installed for this mashup. Team Fortress 2 is required as the companion game. No Dota or TF2 assets are included in the download. This personal challenge panel adds no multiplayer system: you play Dota's normal online matches or bot matches as usual.
