Up From the Depths!

Thirty stories high and crackling with alien energies, it arose: the dreaded Dracostroyer! When the terrible daikaiju strides ashore in the city, are your heroes up to the challenge of stopping it? Fortunately, they have some help from unexpected quarters, including a mad scientist willing to transform them into giant monsters, and a brilliant inventor with a giant mecha in need of pilots.

Dawn of the Daikaiju is a city-stomping adventure for Icons Superpowered Roleplaying that pits your heroes against a giant destructive force. It includes details on Dracostroyer and King Mechakaiser, along with an apprendix for creating your own giant monsters to menace your city and the world!
