The Machine Gunner is part of a group of Chinese MIlitary Soldiers who arrived at the Fishing Village under the guise of securing rations of rice from its grainery - in actuality the military was there to make a foreign weapons shipment. Because of the demons running rampant in the village, the Machine Gunner stayed near the train with the rest of the soldiers.
The Machine Gunner is bald and wears a military tank top. He sprays bullets from his machine gun while ducking and dodging, making him a difficult target to hit when accompanied by his constant gunfire.
Keep rolling to dodge the Machine Gunner's spray of bullets and fire at him during the short pauses when he isn't firing. Do not fire unless the target symbol is visible at the top of the screen, as hitting the box of explosives will cause an instant death for Deke. Deke can hide behind lockers on the right to take cover and peek out the corner while firing. It may take longer to defeat the Machine Gunner this way but it is the safest method of attack.
