Tac-Scan
The Game: Commanding a fleet of ships, you use their combined firepower to wipe out an onslaught of alien ships (which, perhaps not at all surprisingly, are firing back at you). It only takes one hit to lose one of your own fleet, and when your fleet is completely wiped out, the game is over. Until then, do as much damage to the enemy armada as you can. (Sega/Gremlin, 1981)
Memories: I always admired games with novel ways of counting down how many “lives” a player had left until his quarter was declared a total loss. Moon Cresta had a three-stage rocket which could be destroyed stage-by-stage, and Lock ‘n’ Chase featured a getaway car full of extra crooks that could be deployed one-by-one into its Pac-Man-like maze. Tac-Scan gave the player one fleet – and only one fleet – of ships that would be wiped out as the game progressed. When the entire fleet was wiped out, thus ended the game. [read more]
