Oni 2 (Angel Studios)/Running

The ISO can be found on epforums.org (registration required) and is playable on a modded PS2 or in an emulator. The only mature PS2 emulator is PCSX2. Although PCSX2 is available for both Windows and macOS, the Mac version has poor performance and exhibits graphical glitches with this particular game. (Lighting problems occur even when playing on a PS2, so it's likely that graphics code was being worked on when this game build was produced.) Thus, if you are on a Mac, you will ideally want to use Boot Camp to run the game in PCSX2 for Windows. PCSX2 has also been reported to work on Macs running Windows within Parallels Desktop and VMware Fusion; it does not seem to run in Oracle VM VirtualBox, which has problems with 3D acceleration as of v5.1. To prevent glitched shadows when playing Oni 2 in PCSX2, you need to switch the GSdx plugin to Software mode and turn on the "Edge anti-aliasing" setting; this will severely cut performance compared to rendering in Hardware mode.

Once Oni 2 is running, there is only one level available by choosing New Game. Additional levels, however, can be chosen from the Load Game menu. These are documented under "Story and levels" below. Levels can take a long time to load, and some do not have loading screens, instead displaying a gray screen until they're done loading. The only levels that could be considered traditionally "game-like" are levels 1 (The Blast Chambers), 6 (Initial Attack), and 8 (The Rooftops). These were the primary levels used to prototype the game. The other levels were used by the developers to test features or scripting, but some are rather substantial, like level 14 (AI Abilities Test).
