Character Archetypes

I've recently taken interest in the hl2 mod NeoTokyo on the PC. The design of the characters and environment really interests me. Taking elements from Ghost in the Shell, it paints a very beautiful futuristic setting. Being an online multiplayer game, the design of the character classes needs to be very well thought out. The player's team is clearly shown through the color schemes for both factions and class is identified through a verity of different archetypes. Characters with more health are shown as larger characters outfitted with amour to show that they are slow and strong, whilst faster, weaker characters are often smaller and carry less to show maneuverability.
