Vanguard
Description
The Vanguard is the featured Chaos enemy in Chaos 1. It appears in all Chaos difficulties other than Chaos 2. It has relatively low health and deals a small amount of damage. It carries a shield which blocks projectiles rendering them useless.
Strategy
Avoid using projectile attacks unless you are equipped with a piercer servo or piercer chip. Their shield only blocks their front side, so they can also be damaged from behind with projectiles.
Boss Variant
Shield Goblin Gorbstock, the Vanguard boss, has a chance of appearing on wave 5 in Chaos 1. He can also appear on Omega Waves (wave 6) in Onslaught. He is physically bigger, deals more damage, and has more health than regular Vanguards, but otherwise functions the same way as regular Vanguards.
