Oni

Oni is a third-person action game, focused on melee combat mixed with some gunplay. The player can punch, kick, and throw enemies; progressing into later levels unlocks stronger moves and combos. There are ten different guns in Oni, including handguns, rifles, rocket launchers, and energy weapons. Power-ups such as "hyposprays", which heal damage, and cloaking devices, which render the player invisible, can be found scattered throughout the levels or on corpses. Since the player can carry only one weapon at a time and ammunition is scarce, hand-to-hand combat is the most effective and common means of defeating enemies.

There are multiple classes of enemy, each with its own style of unarmed combat. Each class is subdivided into tiers of increasing strength. As in Bungie's earlier Marathon titles, tiers are color-coded, in this case by green (weakest), blue, and red (strongest). Also color-coded are the levels of health each opponent has, indicated by a flash when the player strikes or shoots them. Green flashes show the opponent has high health, red flashes show the enemy is near death.

The events of Oni take place in or after the year 2032. In the game, Earth is so polluted that little of it remains habitable. To solve international economic crises, all nations have combined into a single entity, the World Coalition Government. The government is totalitarian, telling the populace that what are actually dangerously toxic regions are wilderness preserves, and uses its police forces, the Technological Crimes Task Force (TCTF), to suppress opposition.

The player character, code-named Konoko (voiced by Amanda Winn-Lee), begins the game working for the TCTF. Soon, she learns her employers have been keeping secrets about her past from her. She turns against them as she embarks on a quest of self-discovery. The player learns more about her family and origins while battling both the TCTF and its greatest enemy, the equally monolithic criminal organization called the Syndicate.

The game was developed by a core team of about twelve people. The game's universe is heavily influenced by Mamoru Oshii's anime film Ghost in the Shell, with some additional influence from Akira and the works of Kenichi Sonoda. The original plan was for Konoko to be a cyborg like Ghost in the Shell's Motoko Kusanagi. The explanation for her superhuman abilities was changed to be more organic with the addition of the Daodan Chrysalis concept by design lead Hardy LeBel.

Oni was originally expected to be released in the fourth quarter of 1999. Advertising was targeted towards that shipping date, and the game won E3's Game Critics Awards for Best Action/Adventure Game in 1999. However, development difficulties caused the release date to be pushed back continuously. The acquisition of Bungie by Microsoft in 2000 then led to the transfer of the Oni IP to Take-Two Interactive (which owned 20% of the studio prior to Microsoft's acquisition).

The game received "average" reviews on both platforms according to the review aggregation website Metacritic. Some reviewers were unimpressed by the minimal detail of the environment graphics, the lack of intelligence on the part of the AI in some situations, and the plot, which was occasionally criticized as underdeveloped. The game's difficulty in combination with a lack of savepoints was sometimes cited as a negative.

The absence of LAN-based multiplayer, which had been demoed at hands-on booths at Macworld Expos during Oni's development, but removed before release due to stated concerns over latency issues, contributed to some lower scores from reviewers.
