Peroxide

RPGby [Peroxide]Maturity: Moderate · 13+

Peroxide is an anime-style fighting RPG where you battle monsters to grow stronger and take on tough trials that unlock new abilities. Combat revolves around dashing, blocking, drawing your weapon, switching into modes and pushing back against attacks, and you can also carry or grip opponents. A personal spirit realm lets you teleport away and bind your skills.
