Editing Stargate (1981 video game) (section)

===Scoring===
As well as the points gained by killing aliens, scores are also awarded as follows:
* Humanoid falling back to the ground without dying: 250 points
* Catching a falling humanoid: 500, 1000, 1,500, and 2,000 points, depending on number of humanoids carried at the time.
* Returning a humanoid to the ground: 500 points
* Humanoid surviving the level: 100 points per humanoid for 1st wave, 200 per humanoid on 2nd wave, up to a maximum of 500 points from 5th wave onwards
* End-of-wave humanoid bonus: If all enemies are destroyed and a humanoid is falling to the ground, the player receives a 2,000 point bonus if the ship is positioned at ground level directly under the humanoid, so as to simultaneously catch the humanoid and place it back on the ground. If the player simply catches the humanoid in mid-air while above the ground, the wave ends with the player only receiving the 500 points for catching the humanoid.
* If the player accumulates 999 ships and gets awarded another ship, the counter wraps around, eliminating all ships but the one being awarded, and the one currently being played with.

By default, the player receives an extra life, smart bomb, and Inviso energy every 10,000 points. This amount can be overridden when the machine is in maintenance mode. As in ''Defender'', at 9,990,000, those bonuses are given for every enemy destroyed.
