Repulsor and forearm armor, from "Hexagon"
I have made some concept art pieces as a visual support for the cyberpunk novel, titled "Hexagon".
The Hexagon is a futuristic, brutal sport, based on many current others, set in a dark, gritty world with a take on Malthus theories.
This forearm armor piece for the Hexagon player is rigid and rock solid while the flexible armor covering the rest of the arm is weaker and granting mobility.
The undersuit (in red) is not armored, thus, it is a weak point that can be used by the aggressive hexagoners to take down the opponent.
