A nice spaceshooter/space-travelling game written in tasm. You can buy and trade items, upgrade your ship, land on different planets and space stations, fight with space pirates in a huge map that is full with objects, asteroids, ship wrecks and others. In this version you start with more than enough money and if you die the game doesn t stop but your screen becomes a little "messy" (guys, this game remained in beta state :-) IMPORTANT: In game help is avaible if you press F1! It is really needed because I won t tell you here how to control the ship or access the world map! Btw there is a read.me file too, about some technical stuff if you want to know some interesting things...
