The final introductory video for Team Fortress 2 has been released; watch above as the other classes guess what kind of motivation lies beneath the Pyro's stoic demeanor. It turns out he's just a misunderstood psychotic killer!

Today is the third and final day in Valve's Pyromania promotion, culminating in the video above but also bringing new content to the free-to-play shooter. Yesterday saw the addition of Teufort, a new map plagued by raging methane fires, and several new weapons: the Scout gets a new pistol and shotgun, the Sniper gets a new SMG and sniper rifle, the Soldier has a new bazooka and the Pyro gets himself a flare gun, which "knocks back target on hit and ignites enemies in a small radius."
