During the final events of the previous game, the Kreisau Circle retrieves a critically injured William “B.J.” Blazkowicz (Brian Bloom) from Deathshead’s fortress before destroying it with a nuclear cannon. Blazkowicz falls into a 5-month long coma. As he fades in and out of consciousness aboard the Eva’s Hammer (a stolen Nazi U-boat commandeered by the Kreisau Circle), it is revealed that Anya, Blazkowicz’s love interest, is pregnant with twins. The U-boat is soon attacked by Frau Engel, a sadistic Nazi commander and captures Caroline and Fergus or Wyatt (depending on who you let Deathshead kill in a flashback).. Blazkowicz devises a plan to get himself captured and taken to Engel’s airship, the Ausmerzer, which is suspending the U-boat above water. Engel tries to get her daughter Sigrun to decapitate Caroline, but the former refuses, resulting in Engel killing Caroline herself. Sigrun then has a change of heart and tackles Engel, allowing Blazkowicz to use Caroline’s armor. Blazkowicz then disconnects the Eva’s Hammer from the Ausmerzer and flees back to the U-boat with Caroline’s body.
