Expansions and ports There were two official expansion packs released for Quake. The expansion packs pick up where the first game left off, include all of the same weapons, power-ups, monsters, and gothic atmosphere/architecture, and continue/finish the story of the first game and its protagonist. An unofficial third expansion pack, Abyss of Pandemonium, was developed by the Impel Development Team, published by Perfect Publishing, and released on April 14, 1998; an updated version, version 2.0, titled Abyss of Pandemonium – The Final Mission was released as freeware.
