This is a fun little collection of warrior outfits. These were designed for Sword and Sorcery style settings, like Golden Axe, He-Man, Thundarr, etc. Could be for heroes, enemies or NPCs.
If you missed the announcement earlier this week, there's also Villager Outfits to really round out your game's population.
