Tempests appear across the various maps found in Outbreak, and can be usually found in multiple numbers. They are capable of firing projectiles of energy as their main means of attack against the player. When taking damage, Tempests are also capable of teleporting to a different (but nearby) location away from the player's sight. They are also capable of physically striking the player if close enough.
When traveling in a vehicle, the Tempest can temporarily shut it down if it manages to hit it with its electrical projectile. This also has the same effect on the escort rovers.
Tempests are vulnerable to the chest when shot and after taking few hits will reveal their energy core which when enough damage is done will destroy it significantly faster that by other means. Tempests are also vulnerable to head shots, although requiring more damage hits to eliminate it than the chest. Tempests have a teleportation delay when taking damage and can be eliminated a short period after disappearing by continuing to fire without changing focus from that location, especially helpful when in a tight situation.
