Blast
Blast is the seventh powerup in Fortress Blast. It was added to Fortress Blast in version 0.3 and is taken from the game PlatinumQuest.
Blast creates a large explosion at the user's position, damaging every enemy near them. The damage is only enough to kill a full-health Scout at point-blank range (roughly 130 points of damage). This damage decreases the further away an enemy is. Blast also forcibly uncloaks and undisguises Spies, and prematurely stops the effects of Time Travel.
Development information
Players are only damaged if they are less than 250 units away from the attacker and on a different team. Damage is calculated by subtracting 4/10ths of their distance from 150. (i.e. someone 30 units away, multiplied by 0.4 to 12, and 150 - 12 = 138 total damage dealt). Blast is also one of the few powerups to not require any callback.
