Scram 20

Scram 20 is a Scramble clone for the VIC-20.

Fly a small spaceship through a system of caves, guarded by missiles. The player has a gun to shoot down airborne targets and bombs to bomb ground installations. Fuel supply is constantly counting down, so the player must also bomb any fuel containers found on the ground. Later on, the game introduces constant airborne enemies, in addition to the ground-to-air missiles. Scram 20 utilities a character-based scroll, which means that it scrolls quickly, but in increments of 8 pixels.
