Description

Aliens versus astronauts

Mars Mission was built on a simple contrast: astronauts on one side, strange creatures on the other. The Infiltrator is the alien side, a craft that breaks into the humans' base. Four minifigures are enough to field both camps and play out a small conflict. The set is designed for storytelling, yet it also works as a shelf piece for anyone who collects space themes from around 2008, and the shape stands out well in a display. The glowing green helps it read clearly even from across a room.

Lime as the signal colour

The most striking feature is the bright lime green set against black, white and dark bluish grey. That contrast makes the alien elements jump out of the scene and separates them visually from the human camp. If you enjoy colour design, it is a neat example of how a few tones can organise a model. Lime parts are also a popular accent for custom fantasy builds, since they rarely appear in such quantities in other sets.

Size and effort

At 333 pieces the set sits in the mid range, and 109 distinct element types keep the build varied. You are not just stacking bricks; many specialised shapes create the organic, otherworldly look. Plan on a relaxed afternoon. Children of primary-school age can follow the instructions, and adults can treat it as a calm standalone build or as the basis for their own space scenes, perhaps adding a few extra vehicles around it.

Parts list and rebuilds

Further down this page you will find every part number with its colour and quantity, which makes it easier to track down a replacement when something has vanished. The “What can I build?” tool checks which other sets your collection could make, and the lime pieces are easy to pick out for targeted rebuilds. That keeps the set useful long after the alien itself has been taken apart and sorted away. Sorting by colour first makes that search much quicker.
