As you can see from the title, Acheron is an upcoming MMORPG developed using the Unreal 3 Engine. Created by Barunson Games (not the Dragonica developer), Acheron features 2 factions in which players may choose one to side. The faction of Lagperant focuses on using magic, while the faction of Bellum consists of citizens loyal to the usage of machinery. Hmn, didn’t I played some games with the same background story recently…
Supporting pets, called Jinn, may be summoned by players to aid them. It is not known if this is exclusive for Lagperant or will both factions have this ability. So far, the main features are on the graphics, enhanced mob AI with large scale RvR being teased.
Apparently, there will be a PvP feature which allows players to fight and gain control of a floating base. However, it is said that the fight will not be taking place only in the base, but with the whole map being RvR activated, hence much strategy is needed. Gaining the floating base will lead to the conquering side the ability to upgrade several structures found. More information to come when available.
Seen below are some pieces of concept art for the game. Notice the one at the bottom, featuring what is supposed to be the floating base for RvR combat.
