Henri is now fully on his own and resolves to escape the bunker regardless of the war raging outside. Unfortunately, Boisrond is quickly killed by the Beast before Henri could carry out his wish. He gives Henri his revolver, pleading with the latter to end his life so as to spare him a gruesome death at the hands of the Beast.

Boisrond explains that a monster had attacked the bunker garrison and directs him to blow open the exit as it had been sealed by their officers when they fled, trapping the rest of the garrison inside. Salvaging a wind-up German flashlight, Henri traverses the bunker where he comes across a dying Sdt. Henri quickly discovers that something terrible has happened in the bunker while he was in a coma as he comes across signs of violence, blood, and mutilated bodies. Some time later, Henri wakes up in the medical ward of the Central Bunker. Henri is then incapacitated in a mortar strike, dropping Augustin and fading into unconsciousness. As Henri carries Augustin back to French lines, they are spotted by the Germans who open fire. Henri climbs down and offers his friend a canteen filled with the suspiciously invigorating spring water before dragging out. Inside the crater is Augustin, lying wounded against a rock and a signal flare he had lit earlier to signal for help. He soon comes across a deep crater filled with water.

Ultimately, the Germans gas the trenches with Henri seemingly close to death before Lambert arrives, gives Henri a gas mask, and guides him to safety (This prologue acts as the game's tutorial level). Henri traverses through the trench network, being ambushed by a squad of German soldiers, who are then gunned down by Henri's closest friend Augustin Lambert, who instructs Henri to keep pushing towards their rendezvous point. The player assumes control of Henri upon entering one of the trenches. The story starts with Henri Clement sprinting across an active battlefield during the First World War. Meanwhile, during the course of the Battle of the Somme, over five months, the casualties totalled 650,000 from the Germans, 420,000 from the British, and 195,000 from the French-approximately 1,265,000 casualties on both sides. By May, French casualties at Verdun were as high as 185,000 men, and German casualties by the following month totaled roughly 200,000 men. Both battles proceeded with extremely costly outcomes for both the Allies (namely France and Britain) and the German Empire. At this point in the war, the Battle of Verdun had been ongoing for roughly five months, since 21 February, with the French on the defensive, and the Somme Offensive had more recently begun on 2 July, with attacks conducted by the British and French against German-held positions.
