Pause the game and press the buttons. You should notice that one of the buttons will produce a sound with a higher pitch. Now press another button. If you don't get another high pitched sound press the button that first made the sound and continue to try the other buttons. The cheat is a sequence of 5 or 6 buttons. Just think of the game SIMON and remember the sequence until you get it right. You will hear a different sound when you complete the sequence. From now on your life never ends and you have access to the right brain with all weapons available, but all rendered sequences will appear gray shaded only.

When you're about to enter the Pod Bay at the start, and it goes to the cut sequence, pause the game and press the following buttons:

The Title screen will turn black and white and the cheat will be activated. With this cheat, you're invulnerable; you can also warp around the map and have all the guns on the next level you play. To warp around the map, simply bring the map up. There's a solid white block displaying your location and another outlined block, press either the 'Blue' or the 'Yellow' button; to warp to that point, press the 'Green' button. The only drawback to this cheat is that all the amazing cut sequences are in black and white. There are various other codes which do the same thing at different parts of the game. You can find these by pausing the game and pressing all the buttons until you find one that makes a different sound to the others. Press it, then you have to find the next one that makes the same noise. Keep doing this until it makes that noise and the cut sequences are in black and white.

At the start of level one, turn right and at the next crossroads push up. Pause the game, press 'Yellow', 'Red', 'Green', 'Blue', 'Up' and 'Left'. Unpause and you'll be completely invincible.

It seems that Psygnosis has put some music on the CD not used in MICROCOSM. Just try track 2 from the game CD on your audio CD player.

Sometimes you need to warp back to a junction because you took the wrong branch or because of an endless loop you are flying in. Just move to the map and place the outlined rectangle to the red mark you want to warp to (place it with the 'Yellow' or 'Blue' button). To actually warp, press the 'Green' button while you are on the map.
