A Bison on the Moon.

The Bison is an all-terrain rover used in space missions. It is the only vehicles from the Spectrum fleet to come in a variety of colours (grey, red or yellow).

The Moon and Mars Spectrum stations have a small fleet of them, but it can also be carried in the hull of the Spectrum space shuttle as needed.

With its traction supplied by both track and wheel, it is a capable rough terrain vehicle. Its ten wheels benefit from independent suspension, allowing it to go across rocky terrain as well as sand and steep hills. Each wheel has 12 individual plates, which in turn have their own shock absorber. The tracks are also capable of flexing over the landscape. This all means that the Bison can achieve a reasonable speed with great stability.

The Bison can be driven at all speeds both forwards and backwards and is capable of bursts of speed that can propel it over crevasses.

The cabin is pressurized and spacious and can accommodate five people comfortably.

Access to the vehicle is through a door located between the two front wheels. From there it is possible to go to the front cabin, or to the rear section which has storage units and limited accommodations.

Bison's weaponry.

As well as exploration, the Bison can be called on for backup in a military situation.

Armed to the teeth, the Bison features missile racks, pulse laser cannons and a SPIKE electron grenade launcher. It is ready to defend its occupants and any base it is stationed on in a heartbeat.

Should things go wrong, though, the cabin features ejector seats for a quick escape.
