Sega Master System / Mark III / Game Gear
Bomber Raid is a vertically scrolling shoot 'em up in which you fly a fighter craft deep into enemy territory with the intent of causing as much damage as possible.
The enemy haven't reacted kindly to your invasion of their air-space, so expect plenty of opposition. There are five levels in all, each packed with power-up weapons and sporting a giant guardian at the end of each.
It's pretty good fun, but the game isn't difficult to beat, so although you tend to play it a lot at first, it doesn't take long before you finish it and become bored.
