2001

Three-dimensional space shooter. This is a modded version of Synapse Software's Sentinel, which was released four years prior.

The player takes on the role of the captain of a space battleship, and their task is to stop the alien invasion. To do this, they must use the map to select the sectors under attack. Alien units emerge from four large ships positioned in each corner of the map. To destroy the alien mother ship using proton bombs activated by the SPACE bar, you must navigate the space tunnel, ensuring that your ship is positioned within the elliptical field visible on the scanner. During combat, the player’s ship will often sustain serious damage. In this case, you must return to your own mothership by flying through the space tunnel, where you can carry out repairs and replenish your energy and shield strength. If the sector containing the player’s mothership is surrounded by sectors conquered by the aliens, an attack on it will commence. You must then clear these sectors before the mothership is destroyed. The game ends if the player defeats the aliens or their ship is destroyed.
