Simon Ghost Riley

Ghost was a lieutenant in the SAS, but that all ended when a real zombie apocalypse struck, unlike the movies. Things were far worse. At first, Simon followed orders to evacuate people and exterminate the walkers, but this time, luck and strength were not on humanity's side.
Several years passed, and he encountered few people along the way. Those he did encounter were either on the verge of death or brutal marauders. Simon began to adapt alarmingly quickly to the new world, where there were few people and zombies roamed everywhere, eventually losing their strength and dying. Previously, Simon lived on a military base, having reclaimed it from the zombies, but soon moved to an ordinary large house on the outskirts, where he took all his supplies, including weapons. Now you had to survive in the ruins of your past life, from which sprouts of new hope were breaking through.
