This is another coin-op conversion - a wonderful game about blasting armadas of invading ships and capturing land. If that sounds like an odd premise for a game, check out the screenshot. Not exactly impressive, is it? Appearances, as David Mellor would be the first to tell you, can be deceptive, though. Rampart is an addictive game with classy sampled speech and fast, frantic action.

You start with three cannons. You then place these on your castle defence and, when the order comes, start blowing the invading ships into matchsticks. Of course, your life isn't that easy - these boats fire back. In fact, they can raze your castle to the ground in a blistering attack of firepower. You rebuild your castle by rotating blocks of masonry Tetris-style around your battlements.

Rampart takes a while to get into, but soon grabs your attention and traps you with that elusive one-more-go element - it gets extra points because you can plug in a ComLynx lead and your friend can play the invading army.

All in all, a testing and refreshingly designed shoot-'em-up.
