The story is about the wise and benevolent Titans who rule the Earth and use their power to care for other creatures in the universe. The zone of peaceful coexistence they protect is threatened by creatures from elsewhere. To protect themselves, the Titans have formed an elite force called the 'Archangel'. Players take control of this elite force and pre-equip them with over 100 different weapons and items to tackle missions. Soldiers can hear their enemies, and their enemies can also hear them. They can also run, walk and hide, and barrels can explode, fire can spread and smoke can fill the air during gameplay.
It is a turn-based game, and can be played as single player or multiplayer, on random or custom-made maps, during the day or night. It has 26 challenging missions and features an advanced turn-based engine.
