An awesome and underrated entry in the Doom series developed by outsiders who bested the odds and created a fan favorite that pushes John Carmack's aging tech to its limits while evolving the franchise's identity and essence with a spooky, oppressive atmosphere thanks to its gloomy visuals and Aubrey Hodges' excellent dark ambient soundtrack, and manages to rival its predecessors' level of quality thanks to strong level design and a kickass new weapon to surpass the BFG.
