A fresh new DLC-sized DOOM mod for Monster Hunter World introduces players to the fierce Marauder.

Created by modder ‘Lyra’ (and various others), this Monster Hunter World/DOOM Eternal crossover adds DOOM’s Marauder to the game without replacing any other monsters. In addition to adding this fierce humanoid enemy, the DLC-sized modification adds four quests to the game alongside armors and weapons. On top of that, ‘Lyra’ has also included a full Palico equipment set.
