Sometimes it is enough for survival to survive just a minute, and in the game Zone Defender you are given three. The secret base will be attacked by terrible and very dangerous monsters. These mutants attract something to this place and so much that they are ready to die. Your task is not to allow them to cross the red perimeter and hold out for a certain time. These will be the longest and most difficult moments in life. A quick reaction will help you get ahead of the clever and ferocious monsters, killing them before they attack and tear them apart.
