Alphatron
Description
The player's task is to protect the Trilithium refinery on the planet Karthos with the help of a Megan-class scout ship equipped with a Delta laser. Enemy attacks become more frequent, with more waves of enemy missiles flying overhead. The missiles must be destroyed at all costs before they reach the refinery.
Each missile when it reaches its target, depletes its shields. The reconnaissance ship has to often replenish its fuel at the launch site, otherwise it will fall and crash on the planet's surface.
