Each team in Firestorm has two supply depots. Your job is to trigger a firestorm and destroy your enemy's supplies while protecting your own. In other worlds, both teams play offense and defense at the same time.
Firestorm is a two stage process. In the first stage, your team needs to ignite the enemy's supplies. Interact with an enemy supply depot to set it on fire. Once you've ignited the first depot, you have a short time to ignite the second depot before the first burns out.
When a team manages to ignite both of its enemy's supply depots simultaneously, a firestorm is triggered and the second stage begins. A radio will activate in the middle of the map, and it's an all-out brawl to see which team can capture it first. As in Domination, you need to remain in the capture area to get the radio. You can't capture the radio if the area is contested.
If the team that triggered the firestorm captures the radio, a plane will dump gasoline onto the area, igniting the rest of the map and ending the game. If the team that didn't trigger the firestorm captures the radio, a plane will dump water onto the area, quenching the flames and resetting the match to the first stage.
