A fireman gone horribly wrong, the Pyro is the chaos-causer of Fortress Forever. He carries a multitude of flame-based weapons to set enemies alight and burn them to death.
The Pyro's main weapon is the flamethrower. It pumps out a continuous stream of flames and has a huge ammo reserve; allowing the Pyro to harass and control areas for extensive periods of time. He also packs an incendiary cannon and napalm grenades to complete his fiery repertoire. The main tools of a good Pyro are harassment and confusion. On offense, he can keep enemies preoccupied while the faster, more mobile classes make their way to the objective untouched.
The standard-issue crowbar for every class. It does some damage, but not enough to make a difference in a battle against a full-health opponent. It's a good humiliation tool for someone who is about to die, however.
Good for taking potshots if the enemy is out of range of your other weapons.
The signature weapon of the Pyro. The flame stream does considerable damage by itself, but it works best when combined with the stacking damage-over-time effects of the Pyro's other flame weaponry.
Fires flaming projectiles in an arc, which don't do much damage unless combined with the Flamethrower. Can perform rocket jumps similar to the Soldier's.
The basic grenade: A lot of damage, large blast radius. The frag grenade is useful for taking out sentry guns, instakilling scouts or other weak opponents, and general destruction.
Since the addition of flame damage stacking, these are arguably the Pyro's main grenade. He spawns with 2 every life, so make good use of them. A Napalm Grenade has an initial explosion that deals substantial damage and then a bunch of flaming balls (for lack of a better word) scatter around the ground where the grenade exploded. These deal continued damage over time and light any enemy that walks through it on fire.
