Lineage II: Revolution is using the Unreal Engine 4 to create PC-like graphics for mobile devices, and will be releasing simultaneously on iOS and Android. The MMO has four races (Human, Dwarf, Elf, and Dark Elf) and a strong PvP system, as befits a Lineage game.
The mobile spin-off of the Lineage series has seen multiple delays, which have been cause for some concern. Developer Netmarble canceled the planned beta tests back in October and pushed the game from its November launch window. Plus, there is that whole awkward scene with NCsoft suing Netmarble over a different game entirely while the two studios collaborate on Revolution.
