The idea for this costume started after the developers learned about the God of War fans known as the Spartan army. Thinking it would be cool to do a costume that would go with the Arms of Sparta and form a cohesive set of gear, they designed the Legionnaire costume. The helmet design is loosely based on that of a Spartan soldier and the chest plate has elements like the Cerberus silhouettes found on Kratos armour from the God of War flashbacks. The developers also wanted to carry the crimson elements of Kratos’ tattoo and cloth skirt into this costume to keep his palette familiar.
