Demon was created on Cinematronics' vector hardware by Rock-Ola. The flickering is normal :)
| Collecting a crystal | 100 points. |
| Dropping a crystal in the shuttle | 100, 200, 300 etc. up to 1,000 points then back to 100 points. |
| Each second survived | 10 points. |
| Destroying large alien with tail | 1,500 points. |
| Off centre hit on large alien | up to 1,300 points. |
| Destroying a mutated crystal | 400 points. |
* At the start of the game, concentrate on loading as many crystals as you can. Don't worry about the enemy ships yet as they are easy to avoid.
* The mutated aliens with the tails which appear later in the game are worth the most points. You get 1,500 for a direct hit destroying them, but also points for each near non-fatal hit. Get a few hits off-target if you can, as they can be worth 1,300 points each!
* Keep an eye on your shot power remaining and be ready to collect a crystal if necessary to recharge.
* If the shuttle appears on screen level with the bottom block, keep collecting crystals and don't drop any off until the shuttle is clear of the block. You can often lose a life if you are carrying a crystal and can't get to the shuttle before it explodes.
