The Giant

The Giant
The Giant is the first boss to spawn on Day 5. When defeated The Giant will drop:

and a chance for voltage circuits, drones, and computer chips.
 * 1 Small Key #3
 * 1 Plastic Armor
 * 5 cooked meat
 * 50 units of oil
 * 5 piece of gold
 * 1 Radioactive Material
 * 1 semi-auto shotgun

Combat
Prior to engaging the giant, be sure to equip a robotic suit, use an adrenaline shot, have healing items on standby in the quick slot and have plenty of ammunition.

The enraged state of phase 2 can easily be kited if the player begins to move at an angle approximately 45 degrees inward of the giant's path while it charges.

The Heavy Machine Gun and Railgun are the most effective weapons for dealing with this boss.
