It is the Skyrim to Fallout 3’s Oblivion, if you will – it iterates on the previous game’s already amazing systems, and it’s similarly dense with locations to explore, genuinely creepy monsters to fight, and superbly engrossing post-nuclear atmosphere that blends unsettling gore and death with dark comedy.
Most of the way this huge roleplaying-shooter game works is carried over from its excellent predecessors, Fallout 3 and Fallout: New Vegas.
