Operation Flashpoint (OFP) aka ArmA: Cold War Assault (CWA)
Oxygen 2 is actually the real full version of “O2” model editing program by bis. They released “Oxygen Light” to the community, but for simplicity and common practice, we just call the released lite version “Oxygen 2” or in short “O2” here at PMC Editing Wiki.
O2 is used to edit OFP P3D model files, it only reads/saves MLOD models.
