Hartacon is an online RPG game that allows people to challenge each other in multiplayer battles. It is not a MMORPG. Each player will have the opportunity to create one or more parties with a given amount of Upgrade Points (UPs). Adding characters to a party and buying equipments consumes the party's UPs. UPs can be gained by playing online battles. Characters gain Growth Points (GPs) when they level up. GPs can be used to buy skills and increase stats.
