В игре тупейшая механика сохранения. Если твою базу вынесли, то игра объявляет о провале миссии и тупо перезаписывает мое сохранение где у меня еще дела шли хорошо. Нет разных слотов сохранения миссии, это про жесть, у меня нет слов. Это худшая стратегия в которую мне приходилось играть.

Наиграл в общей сложности в эту игру за 300 часов. Перепрохожу стабильно раз в полгода. Хороший, годный сплав тавердефа и экономической стратегии, много приятных мелочей вроде древа развития и достаточно хардкорных одиночных миссий в кампании. Видно, что, разрабы долго полировали механики и баланс. К слову, имеет место реализация самых отбитых стратегий умерщвления зомби, что повышает реиграбельность и удерживает интерес. Если случится чудо - попробовал бы когда-нибудь либо кооп, либо продолжение, т.к. уже давненько настолько не залипал в подобные тайтлы.
