Metal Arms – Glitch in the System – XBox

Metal Arms - Glitch in the System - Platform: XBox

Fighting the Zombiebot King: 
----------------------------
In order to beat the Zombiebot King just wear him down using 
rockets until he pauses (doesn't move). Toss a grenade 
(coring charge) into its mouth. On Normal, it takes five 
grenades to kill him and after the 3rd and 4th grenades 
there are regular zombiebots that swarm the arena

Note from the dev team:
----------------------- 
In the "You Know The Drill" level, tether the Predator. 
Then pick up a secret chip. Look at the mission objective 
in the pause menu for a note from one of the level designers. 
(The designer himself hinted at the easter egg in a GameFAQs 
MA: GitS board topic.) 

Original Concept Movie:
----------------------- 
To unlock the original concept movie, finish the whole 
Campaign (Story) mode.
