Everyone is a pyro, and your goal is to survive. Airblast rockets aimed at you and your team to reflect them and wipe out the other team!
Rocket Speed: Usually, rockets will speed up and their damage will increase after each successful reflect. This resets back to normal when the rocket explodes, but not in all maps - see below.
Watch out though, if you stray too close to an exploding rocket, you may get caught in the blast.
Beware of Nukes!: They do damage over a large area, and can reduce your numbers very quickly. Don't miss them!

Map objectives: Some maps have slightly different game modes,twists, and objectives. For example, it may be an arena-style map where you only get one life. In other maps, you will respawn but your goal is to capture intelligence or a control point and hold it until the round ends. Still other maps let you respawn, but the rocket speed does not reset upon death.Yet other maps may have obstacles you need to avoid, such as trains, or introduce environmental hazards.
