Sega Master System / Mark III / Game Gear
This game was a sensation when appeared in 1986, and this version has all the features of the original machine.
Each player (and there can be two at once) selects a character - either the Valkyrie, Elf, Wizard, or Warrior. Then you're thrown in at the deep end - placed in a huge scrolling dungeon full of creepy creatures and malevolent monsters! All you have to do is make your way to the exit - not easy because there's a vast army of creatures out to knock down your health points.
The levels are littered with treasure chests, which give bonus points when collected Food can also be found which adds 100 points to your health, and there are also potions which give temporary benefits such as invulnerability and spells which damage or kill everything on-screen when unleashed.
The game is played at a tremendous speed, and each dungeon is packed with literally hundreds of vile and gruesome creatures all out to get you - as you can imagine, it's action all the way! As well as being very playable, the graphics and sound are also excellent. The sprites are small, but they're superbly detailed, and the backdrops are very polished, giving the game a true arcade look.
With 100 different levels to challenge you, Gauntlet won't lose its appeal in a hurry. If you've got a Sega, do yourself a favour and plug this into it.
