Want to enjoy a game, not have to mute it due to all the constant screaming. If I wanted that, I'd still be married. Why do I still get notifications when I turned them off. I want to remove my progress of my account and delete this perm.

"UNDEAD FACTORY: Zombie Pandemic" — оригинальный симулятор управления зомби-фабрикой. Игра сочетает стратегию, исследование и элементы гонки против времени. Погружение в атмосферу апокалипсиса усиливает графикой и звуком. Увлекательно развивать производство, улучшать технологии и противостоять врагам. Однако сложность баланса и ограниченный выбор миссий снижают повторяемость. Подойдет фанатам жанра с любовью к нестандартным механикам.
