Description
A base inside the mountain
Power Miners tells of miners who search deep underground for glowing crystals and run into hostile rock monsters along the way. The mining station is where equipment, vehicles and crew come together. At 636 pieces it is one of the larger sets in the line. It works as a headquarters, and other sets from the series can be grouped around it so the story keeps going, until a whole mining landscape has grown across the table or carpet.
Four figures, plenty to do
Four minifigures make sure something is always happening at the station. You can place workers at different spots, post guards and organise transport runs. Play here depends on several people having jobs at once, taking turns or helping each other out. If you add crew members from other mining sets, you quickly have a proper little team, which also makes longer play sessions much more rewarding and keeps them from getting dull.
Black, grey and a touch of lime
The main colours are black, dark bluish grey and light bluish grey, with lime added on top. The dark tones suit life underground, while the bright colour adds accents that read like energy sources or warning markings. With 156 different part types there are plenty of special shapes that suit machinery and technical details. If you enjoy tinkering with small things, you will find a lot of material here and can extend or reshape the station later to your own taste.
Reuse and rebuild
The parts list on this page helps when checking second-hand sets or ordering missing bricks. With “What can I build?” you can see which other models are hiding in your stock once the station has long been taken apart. The many grey and black parts are in demand for vehicles, factories and science-fiction builds that have nothing to do with mining, and they slot into almost any gloomy scene. That is why the list is worth a look even if you only see the set as a source of spare parts.
