Final Doom: The Plutonia Experiment + Complex Doom Trailer

Complex Doom is a significant modification (Mod) released in 2017 for PC, built upon Doom II: Hell on Earth and requiring the Zandronum source port. The core gameplay loop involves fast-paced shooter action, but it is fundamentally altered by comprehensive overhauls: you will encounter redone weapons, redesigned enemies, and adjusted power-ups. This modification focuses on delivering a fresh, challenging experience by completely reworking the base game's core assets, including new graphics and sounds.
