Final Doom: The Plutonia Experiment (D44D)
Playthrough of Final Doom: The Plutonia Experiment, with 100% completion* (100% kills, 100% items, 100% secrets), using the Doom 4 For Doom (D44D) mod.
*Almost. Sortakinda. Only reason I couldn't achieve 100% was due to D44D mechanics interfering with normal gameplay and causing issues. So it's more like 99.96%.
