Demoneye-X (c) 1981 Irem Corp.

Fearsome Unknown Creatures Close In. Now, A New Terror Spreads Out Across The Universe !! The player moves his spaceship to the right and left with the control lever and fires missiles by pressing the Fire button.

When all the small demons have been shot down and the super-demon is hit in the heart, the screen is cleared.

- TIPS AND TRICKS -

* Hint 1 - The Small Demons Change Their Shapes Three Times : The first demon shape (Demoneye-jr : 40 pts) turns into the second (Octoplus : 70 pts) and the second into the third (Octobomb : 100 pts) when they are shot. Care must be taken to prevent Octobomb ramming into the spaceship.

* Hint 2 - Bonus Chance for 3-Demon Formation : Sometimes Demoneye-jr and Octoplus change their color. If Octoplus are shot while their color is changing they will turn into a group of three Octobombs. If all these three demons are killed a bonus point is scored.

* Hint 3 - Aim At The Heart Of he Super-Demon : When all the small demons have been wiped out, a hole appears beneath the body of the Super-Demon (Demoneye-X : 500 pts). This is the Super-Demon's weak point. If the player can shoot the Super-Demon in the heart he can destroy the creature.

* Hint 4 - 3-Eyes Demon King Appears : If the player succeeds in a series of two games, a three-eyed demon king appears (Demoneye-King : 1500 pts). To destroy it, the player must hit its heart 3 times with his missiles.
