Giant

A Giant is the most expensive unit in terms of Gold in every single Stick War game, and with good reason. These massive beasts have unmatched health and Stunning smashes that can demolish a Swordwrath charge and turn them into a bleeding mass of bodies. Their decisiveness in battle as a firm backbone is invaluable.

Stick War
Giants enter Order's campaign in the No Man's Land level. Attacking in singles (which is still dangerous), Giants use spiked clubs and mutilated bodies as weapons, and when they attack in pair towards the end of their Statue's health, you better hope you have room to fall back. Once they are beaten, Giant growth can be upgraded to make them 20% healthier and larger, and the race still tries to crush you in subsequent levels. In the last Stand, a GIANT Giant (Giant compared to a Giant), is released from their statue encasing, and order must regroup to slit this last challenger's throat.

The same will most likely apply for Stick War Legacy.

Stick War 2 - Order Empire
Giants have a more descriptive role in Stick War II. It is revealed that they agents of Medusa's Chaos Empire when Order captures one and makes him an Enslaved Giant. They still use their chosen weapons. Medusa herself is the new boss though.

Stick Empires
For the Chaos Empire, Giants acts the same as they did in Stick War 2 - Order Empire. Also, they can be upgraded to have more health and size (two times).
