On May 12th 1999, id Software published “Quake II: Quad Damage”, a compilation that included Quake 2 and its two mission packs - The Reckoning and Ground Zero, as well as NetPack I: Extremities.
Macmillan Digital Publishing distributed a Linux version under the name “Quake II: Colossus” (but this version did not contain the Netpack)
