Zerg Hex is a Starcraft 2 arcade game that requires a decent amount of team work. There are the Terrans who have to defend themselves against their common enemy, the Zergs.
On the Hex, Both Terrans and Zergs start somewhat weak. Zergs have the upper hand in defense. They can then decide to balance between aggression, to prevent the Terrans from growing to quickly, and economy, to keep up with the Terrans as they tech up. Zergs rely on spawners to create an army and Mineral Extractors to get more money.
The Terrans start out with their main base. Each base has a Command Center, a Barrack and a Generator. Terrans, unlike the Zergs, have Laser weaponry which require Energy. Energy which their Batteries hold. Terrans deal with three types of supplies (Energy, Minerals, and Vespene) unlike the Zergs which only need Minerals and Supplies.
