The Griffin is capable of performing airstrikes on terrestrial targets.
After escaping from the Defenders of Man, Agent Nova Terra met with Emperor Valerian Mengsk, who promised her the Griffin and his covert ops crew in return for her loyalty. She accepted, and after recovering some of her memories set out for Tarsonis.
The Griffin deployed her and her crew outside of a Defenders of Man base, allowing them to garrison structures surrounding the base while Nova Terra infiltrated the facility.
After discovering the Defenders of Man's plans to stage a feral zerg attack on Tyrador IX, Nova took the Griffin through the zerg forces in orbit and established a base near their hatcheries. After fighting the zerg and Tal'darim, Nova and her covert ops crew escaped the planet. However, the Griffin was boarded by HighlordAlarak of the Tal'darim. Alarak made a bargain with Nova, and lead her and the Griffin to the planet of Jarban Minor. There Nova was to gather terrazine to undo her mind wipe.
With her memories slowly becoming restored, Nova took the Griffin to location of the last mission she remembered doing for the Defenders of Man; the city of New Andasar on Antiga Prime. Nova took the Griffin to the surface, and dropped forces to establish a forward base. After she recovered her memories and discovered the leader of the Defenders of Man, General Carolina Davis, Nova left Antiga, and contacted Emperor Valerian Mengsk aboard the Griffin.
Later, the Griffin deployed Nova to Vardona, where she was to capture Davis while Valerian gave his speech. The operation was a success, but soon after her capture the Tal'darim attacked the city. Nova's forces from the Griffin rushed to the defend the city, and together with the Dominion military and the low ranking Defenders of Man, were able to push back the Tal'darim and inflicted heavy casualties on their Death Fleet. However, in the chaos General Davis escaped aboard the Medusa, and the Griffin gave chase.
Soon after though the Griffin lost the Medusa, and spent hours looking for leads. Eventually the Covert Ops Crew found it, as the Cerros Shipyards were under attack by a lone Dominion vessel. The Griffin was sent to the shipyards, and deployed Nova's forces to reinforce the shipyard defenders. Nova's crew fought through the Defenders lines, and fought the experimental Xanthos war machine, downing it. However, after the Xanthos's defeat Nova violated direct orders from Valerian, infiltrated the machine's hull, and assassinated Davis.
Now branded as fugitives for violating Valerian's orders, Nova talked with Reigel in the cargo bay of the Griffin. He told her that the ship's crew were loyal to her alone, and would follow her wherever she ordered. Nova stated that the Dominion would always have enemies, and they would need to defeat them their own way. Now on the run, the Griffin headed into an asteroid belt. Admiral Horner tracked the Griffin, but Valerian ordered him to let them go, for now.
The Griffin serves as a calldown for Nova in Co-op Missions. Its abilities are listed on the top of the screen, and can be cast anywhere on the map. These abilities include transport and calling in airstrikes. Each of these abilities costs minerals to use.
The Griffin allows the player to outfit their army with special upgrades. Each upgrade can only be equipped on one unit at a time, and each unit can only be equipped with one upgrade. While the same upgrade may be available for different units, it will not always function the same way.
