- "The ZRS-6 has been outfitted for ground strikes with high yield explosives."
- — In-game Description
The ZRS-6 Dirigible is an airship, but differs slightly from other Air units. It is designated as an "lighter-than-air" (LTA) unit type, and there are a few attacks that target LTAs specifically. Also, many -based attacks that normally cannot target air units may be able to target LTAs.
The Dirgible first made an appearance in the 3.0 Dev preview video. When the Anti-Aircraft Flak Gun was first introduced as a limited time purchase, the mission, Give Them Some Flak, pitted the player against a few enemy Dirigibles.
The ZRS-6 Dirgible was first available to players as the Tier 7 reward for the second Boss Strike event, The Battle of Shaman Kuros. It was later brought back as a Tier 3 reward for the sixth Boss Strike event, Evaline Acehart's Airstrike.
The Dirgible has two attacks. The first is a single target strike with a higher critical chance against Soldiers. The second attack is a 5-diameter attack that practically covers the entire battlefield, showering the enemies with multiple, weaker strikes. Both these attacks also inflict a fire-based damage-over-time effect (). Note that the second attack will inflict much weaker DoT damage due to the fact that the attack is a (x3)-type attack, and DoT damage is based on only one of those attacks.
While the ZRS-6 has good damage potential against ground units, it lacks any sort of anti-air abilities.
- The ZRS-6 Dirgible is based off the German zeppelins used in bombing runs during the first World War.
- Added, yet available only through Boss Strike.
