Doom Eternal - 100% Ultra-Nightmare in 2:59:18 [4K/60FPS]
Of course I had to do a 100% run as well. 2:59:18 is an estimate of IGT (In-Game Time), Real Time (RTA) is roughly 3:01:08 where time starts from when I gain control (0:33) and ends when IoS death cutscene begins (3:01:41). Obviously since IGT is the standard people use and it's sub 3 hours I'll go with that ;)
100% means all weapons upgraded, obtain all sentinel crystals, tokens and collectibles, unlock everything in the fortress, get all codexes and get all weapon points. This should leave you with 8 w
