In the distant future, earthlings went out into the distant cosmos and began to base on the planets colonies in which the settlers from the earth lived and worked. Quite often they were guarded by soldiers from the star fleet of the Earth. You in the game Terminus will have to destroy the monsters who want to attack the settlers. Taking up arms you will take a position on a special tower. You will have to aim at these creatures and shoot at them. When you hit your charges, they will explode and you will be given points.
