 
								Sentinel is a 1-player Tempest clone for the BBC Micro. In a far quadrant of Space Sector 4 are the compressed single-dimension gateways to the anti-matter world of Migon. The player controls a spaceship that can rotate clockwise or counterclockwise around the 16 spaces on the outside of a square. The ship fires towards the center, and tries to destroy incoming enemy vessels before they reach the peripheries of the level. Some enemy vessels rotate around the peripheries of the level threatening the player. Once per level, the player can fire their Star Smasher, which destroys all enemies on the screen. At the end of each level, the player must avoid meteors that stream towards the edges of the screen. The player starts with three lives.
