// Excalibur(1988)

Excalibur is 2D arcade side scrolling shoot'em up game. The game hasn't real story and has quite a simple game play - the player controls a red space ship, flies straightforward, avoid obstacles and shoot enemies in various locations (mostly mountains with space background). The enemies are in many types, shapes and colours - spaceships, "molecules", geometric figures, etc. If a spaceship flies too slowly, then it has a tendency to fall down.
