Rapier Punch is something of a miracle as far as programming goes. Someone has managed to fit 100 screens into an unexpanded Vic!

Each level is set in a darkened room. Somewhere around you is a treasure chest and you have to find it. But there are enemies in the room with you and you may not be able to see them until it's too late.

As the game starts, the screen is black with a while square in the centre. You are at the centre of the white square and this shows you how much you can see in the dark room.

You move yourself with a joystick and, as you walk round the screen, so more of it changes from black to white. This will reveal the whereabouts of the treasure chest and everything else in the room.

The objects include dragons, dragons' eggs, spinning crosses and barriers. Barriers are small blocks through which you cannot move. Dodging them would be easy until you remember that you can't see them until it's too late. Crosses can be destroyed at certain times, but often they will destroy you. Their fate depends on the sounds which the computer is making so you have to listen carefully.

You can fire at the enemies, but if you hit a dragon's egg then it will hatch and the dragon will start to fight back.

At the top of the screen, a timer ticks away. You have to find the treasure chest before you run out of time, otherwise the game is over. You receive a bonus for reaching the chest depending on how fast you managed to find it. And for every 10,000 points, you get an extra life to add to the three which you started with.

If you're always on the lookout for good games for your unexpanded Vic, then you've found one in this game. It's not Jet Pac but there again it's not Mastertronic either.

The graphics are reasonable and there's even sound effects as well.

This will certainly keep you occupied for some time as you try to explore all 100 rooms.
