The Chemplug upgrade, unique to Epsilon's Scorpion Cell subfaction, grants them full technology access and a variety of support powers based on their chemical research. Upgrading the Pandora Hub to acquire the complete weapons array and accompanying support powers can give an Epsilon Proselyte the edge he needs to overcome his enemies in battle.
Other than granting the proselyte the wide array of chemical warfare his affiliated subfaction has to offer, the Chemplug also provides the following support powers:
4 Dybbuk-Strikers are summoned to bombard a designated area with explosive toxic shells effective against infantry and light vehicles. Unlike the rest of Epsilon support powers, this one requires an active Aerodome in order to be accessible. Also, this support power costs $1200 and takes 7:00 to recharge.

3.0 Pandora Hubs with their respective plugins. Note the chaos gas in the Chemplug.
In version 3.0, the Chemplug, along with its equivalents, only costed $500 and only provided the support powers of its respective subfaction (in the case of Scorpion Cell, they were the Molebomb and Weaver Trap), as the Pandora Hub alone was enough for Tier 3 to be unlocked. Also, half of the containers in the Chemplug were filled with chaos gas.
