Eternal Doom IV: Return from Oblivion

Eternal Doom IV: Return from Oblivion is a hub-oriented episode WAD for Doom II and the ZDoom source port that was released in January 2008. This TeamTNT release followed on the third installment of Eternal Doom with a 7-map demo, and reuses some of its resources, but the intended full megawad never materialized.
