Red Stone tries to capture the feel of older RPGs with a few more modern twists. In the 2D MMORPG from L&K Logic, the usual quests, hunting, and leveling options are there, but things like the Charge Point system and the ability to transform skills and weapons at any time add variety. Charge Points, or CP, are a system by which special attacks are carried out and replenish with successful hits. However, fighting while in motion decreases their rate, so a certain degree of strategy is necessary.
The ability to change classes and weapons balances the difficulty and gives the ability to patch holes in a group's weaknesses.
