Zeus lander

The Zeus Lander is an unused unit from Galaxy Map Editor files for StarCraft II: Heart of the Swarm.

The Zeus Lander is a modified hercules dropship, a massive transport ship able to carry 30 units at a time, deploys them almost instantly, and if the Lander is destroyed the units inside are ejected to survive, albeit slightly wounded. The major difference is the Zeus Lander has much more HP, as well as an attack used to combat air units. The attack is similar to the battlecruiser, rapidly firing laser blasts at targets.

It is possible the zeus lander was a militarized variant of the hercules dropship in the same way there was a militarized variant of the armored personnel carrier in the game files. The assets for the Zeus Lander refer to it as "militarized colonist ship," making this explanation more probable.
