Bruce To The Rescue

Don your jetpack and tackle the robots in the search for your fair lady in this game from Andy Clarke for you to key in to your Commodore 64

Bruce, for the Commodore 64, presents you with a few tricky problems. You are Bruce, equipped with a jet-pack and searching through robot-infested caverns. Your goal, Bruce, is to find your girl - we assume she's called Sheila...

In order to play the game you'll need a joystick in port one.

Playing The Game

Level One

At this level you have five lives to play with and can move in eight directions. You being at normal speed. Pressing the Fire button once takes you into top gear - press it again and you revert back to the normal pace.

Your objective is to collect three cannisters of fuel before your bonus runs out, without touching any aliens, robots or electrified girders. You get 1000 points per cannister but if you lose a life you forfeit the cannisters you're carrying.

To get on to level two without going through the first section you can cheat by pressing Run/Stop while level one is underway - then type Z=3:CONT and press Return.

Level Two

You'll need some nifty work with the joystick and speed controls to get through this level. To rescue Bruce's girl you have to duck between girders, avoid aliens and get three fuel pods and the sword.

Moving in only four directions it's advisable to go for the sword first - once you've got it you're invincible. When the sword, three aliens and three fuel pods have been taken the game ends.
