The Ultralisk in Starcraft 2 is a BEAST! I am rarely impressed by short vids of unit combats but when 1 unit can destroy 798 zerglings, that is impressive. The Ultralisk has 3/3 full upgrades and the zerglings are 0/0. The Ultralisk has 6 Armor, 600 hp, and hits for 24 splash damage with a very fast attack speed (it has a cooldown of 0.86 seconds on normal Setting). Zerglings have 35 HP,? no armor, and hit for 5 w/ a cooldown of 0.58. After Armor, the Zerglings are hitting the Ultra for 1.
