The Boulder Tower is the second tower available for the Blood Elf Engineer to build in the "secret" Frozen Throne Human Campaign level. It was also found in the Warcraft III Frozen Throne Expansion Human Campaign protecting the Draenei base and in the scenario map Blizzard Tower Defense. It has a lot of piercing damage and can only attack ground units.
