Dark Base was really great game from the first episode. But you were moving in chaotic area and the number of enemies was low. But this third part is really absolutely top among the freeware games. You don't move inside a specshuttle but you have huge outside place to explore. The mission are separated into night and day. The night are very unpleasant because the enemies move quickly and are hard to kill. The missions need your full concentration and you cannot decide yourself but when you have free movement you can do what you want and clean sectors according you wishes. Level up and get better weapons as Hurricane R6, better mines and other things. The game offer enormous portion of fun and possibilities.
