Ultralisk (StarCraft)

The ultralisk is a heavy zerg ground unit in StarCraft.

Overview
The ultralisk's attack is hardly impressive for its cost and high tier. Its main advantage is durability, staying power and fear. The ultralisk may lead an attack and draw the first volleys of defensive fire allowing more of the lesser zerg units to survive and close to attack. The ultralisk's relatively slow speed requires some planning to get it to the front rank before the attack. Its large footprint may hinder it and its allies at choke points in addition to making it difficult to reposition once caught in a melee.

Ultralisks, while having strong armor, are not very effective against groups of units that deal explosive damage or large amounts of it; this includes siege tanks in siege mode, mass dragoons, reavers, dark templar and occasionally, groups of zealots. Spider mines are also effective against ultralisks. Other counters also include archons with support and the battlecruiser's Yamato Cannon which can take down more than half an ultralisk's hit points. Psionic storms and Irradiate are also capable of damaging ultralisks severely though not directly killing it.
