This is an old, but classic 80s game which used vector graphics. Although not as well-known as some of the other games on this site, it is both simple to play and very addictive.

Originally created in 1980 by Cinematronics, the object of the game is to obliterate a series of defenses circumferencing a stationary turret in the centre of the screen. Just use the arrow keys to move your ship and the spacebar to fire.

The game featured in the 1986 movie Maximum Overdrive. The player was electrocuted by the arcade game, which won't happen when you play the online version below - I promise!

Star Castle's designer, Tim Skelly, also created the 1982 monochrome vector arcade games War Of The Worlds and Armor Attack.
