Until We Die is an exciting action game with strategy elements and a side view, where you have to defend your base from the invasion of extraterrestrial monsters. The base is the metro station and its underground part. To win the game you need to survive about 30 game days, repelling all attacks on the base. At first there will be small flocks of creatures, and at the end there will be a horde of mutants sweeping away everything. Also, the game will end earlier if the main character, Ivan, dies, or the electric generator, the heart of the base, is destroyed.
