Here are some tricks for Lego Rock Raiders.

1. On some missions you have an air bar. Your air bar goes down faster depending on how many Rock Raiders you have. Build a support station to stop this bar from going down.
2. Always have laser beams or any other tools of defence ready just in case.
3. Always build electric fences around your base after you get a power station.
4. Electric fences do not work on slimy slugs. To stop slimy slugs from coming, build power paths around their holes.
5. Try to construct Rock Raider HQ as soon as possible.
6. Never use dynamite near people, buildings, or vehicles.
7. Build power paths often to make Rock Raiders run faster on them, but don't go to overboard.
8. Never build pleasure buildings you won't use.
9. Keep a good supply of energy crystals handy.
