Duality
Duality is an abandoned video game project set in a futuristic megapolis, with visuals that resonate with Oni and Oni2 themes.
Like Strident, Duality was developed by Trilobite Graphics / Phantagram Interactive (Korea) in the early 2000s.
What We Know
Duality never made it to beta stage, and there are no detailed accounts of the game's factions or gameplay details.
The biggest source of information on the game's factions and entities is Alberto Gordillo's portfolio on ArtStation.
There seems to be at least three main factions - TechCorp, BioCorp and Templar -, each with their areas of influence.
The corporate districts are complemented by a dilapidated "Underworld", possibly ruled by another dominant faction.
Each of the three main factions/corporations has an "intranet" (VR environment) that can only be accessed on-site.
A vast public cyberspace also exists, apparently overseen by an "A.I. council".
Fantastic locations exist within the cyberspace, among them a "VR sanctuary".
The only named character we know of is "Cpt. McKenna" (owner of the "Electric Sheep" club?).

Trailers
There are two trailers. Neither of them is overly exciting.
The trailer follows a Hacker (she) and a Mercenary (he) as they break into a heavily guarded facility (TechCorp?), steal some important stuff, and then escape.
The Mercenary uses regular stealth, acrobatics and weaponry, whereas the Hacker spends most of the time in the enemy faction's intranet fighting weird monsters.

Another full version (crappier resolution but without a watermark): https://www.youtube.com/watch?v=up8r2Dj8bMo
The segments published by IGN are dated April 8, 2002, and labeled "Gameplay", although the trailer is clearly staged/rendered (not unlike Oni's first trailer).
This trailer is higher-resolution and shows some actual gameplay (mostly stealth), as both the Mercenary and the Hacker make their way through enemy territory.

The final sequence of that second trailer is a hint at the third playable character - the "Virtual Being". Apparently it plays chess.
