Toxin shells

"Toxin shells upgrade complete!"

- Scorpion pilot talking about the upgrade

Toxin Shells are tank shells used by GLA Scorpions and Marauders and can be purchased at the Palace. After the upgrades, these GLA tanks will fire with shells laced with toxins (which will remain in the area for a short time), making them more effective against infantry. The toxin may be upgraded to Anthrax Beta and (in Dr. Thrax's case) Anthrax Gamma.
