Sept

The Sept are the main villains in the ZX Spectrum/Amstrad CPC game Marsport.

Story
The Sept are a insectoid alien race which originate from the planet Gath. Structured in a hive-mind society, the Sept have reached the Solar System around the year 2424, at which time mankind had already begun space travel, constructing many facilities on the neighboring planets. The Sept began attacking Earth in an attempt to take it over and destroy mankind, occupying many of these human facilities. The conflict between humans and the Sept would span over decades, with the Sept only being kept at bay due to a large force field protecting both Earth and the Moon.

In the year 2494, the force field around Earth starts to weaken, so in order to fix it a mission is started to retrieve the project's original plans, which are stored in the Martian underground base of Marsport, which had been abandoned at the beginning of the Sept invasion and is now under the Sept's control. To accomplish this mission, the Terran Underground Organization sends in Commander John Marsh, who is tasked with invading Marsport and restoring it's central computer in order to find the plans and escape the place alive.

During his mission on Marsport, John Marsh faces two kinds of Sept: the Sept Warriors are small humanoid insectoids who walk by jumping and will attack the hero on sight. He will also find the Sept warlords, giant and immobile monsters who block his path on key areas.

Trivia

 * Marsport was supposed to be the first of a trilogy of games called the Siege of Earth. It would be followed by two sequels titled Fornax and Gath, which would take place centuries after Marsport and have mankind exploring space while fending off the Sept, eventually attacking their homeworld and returning to Earth for a final showdown. However none of the sequels were ever produced.
