Dynamite

Info
This upgrade deals damage in a small radius each time your tank dies.

Note that the damage is dealt when your tank explodes, not precisely when you lose all your health. The damage radius is roughly the same as the explosion.

Rare
600 damage

Epic
900 damage

Strategy
Equip Dynamite when you expect your tank to die often. Many of the long-range tanks are fairly fragile and would seem like ideal candidates, but the close-range tanks are usually both receiving more damage and are close enough to the enemy for Dynamite's radius to affect them.

Note that, despite the relative rarity of this upgrade, it is a fairly common one for AI-controlled tanks to have equipped.
