Shields are one of the common Powerups found in the BattleTanx Series.

Upon picking one up, the players current tank will surround itself with an energy field, protecting the tank from enemy fire. Additionally, all weapons fired at the shield will be rebounded. This shield will last until it has taken a significant amount of damage, after which it will wear off.

Shields can withstand a Nuke explosion, but will wear off immediately after.
