At the end of the Sentinel Prime mission and its battle with the Gladiator, you'll have to deal with a few issues aboard the Fortress of Doom before you can continue your adventures in DOOM Eternal.
Next, head to Taras Nabad for the 9th mission. This is certainly one of the toughest missions, as it involves unique mechanisms.
It's especially important to be thorough in your level search if you want to get all the Milestones.
