Oni is a third-person action game developed by Bungie West, a division of Bungie Studios, and released in 2001. It was Bungie West's first and only game. It broke new ground by blending third-person shooting with hand-to-hand combat, resulting in a unique, yet familiar game for third-person shooter enthusiasts. Due to difficulties in debugging and the general unplayability of a fighting game over anything with higher lag than a LAN at that time, multiplayer was omitted from the released version. The game's universe is heavily influenced by Masamune Shirow's manga series Ghost in the Shell.
