Lego Rock Raiders


Lego Rock Raiders was a Lego theme focused on mining equipment that released in 1999 and 2000. It was the only underground-based Lego theme before Lego Power Miners. The theme, while short-lived, featured sixteen construction sets and numerous story-related media, including three books and a video game.
The premise of the theme involves the crew of the space ship LMS Explorer. The vessel is damaged and drained of power after wandering into an asteroid field, and is pulled into a wormhole that flings it into a distant galaxy. The Rock Raiders scan the nearest planet and find that it is abundant with energy crystals. The Rock Raiders, while repairing the ship, must venture down inside the dangerous caverns in the planet to mine the precious energy crystals to power the ship.

Books and comics

Three books and a number of comics about the Lego Rock Raiders theme were published.
There were also small promotional mini comic books included with specially marked, first edition releases of the main eight Lego Rock Raiders sets from 1999.

Video game

A real-time strategy video game of the same name as the theme was developed by Data Design Interactive and released for Microsoft Windows in 1999, with an action-adventure PlayStation game following under a year later.

Theme

Characters

There are six characters in the Lego Rock Raiders theme.
Energy crystals are yellowish-green crystals that contain vast amounts of energy, and are the main sources of power for the Rock Raiders. However, they also serve as the primary food source for the monsters and slugs on Planet U, often resulting in conflicts between them and the Rock Raiders. Energy crystals were introduced in Lego Rock Raiders, and have appeared in several themes since then.
When an energy crystal’s energy has been depleted, either by use of a Mining Laser or by Slimy Slugs, it turns either a dark gray or a purple color and has to be recharged at a Recharge Seam.
A rare variety of red energy crystals, five times more powerful than normal green ones, appears in the PlayStation video game, where they serve as bonus pickups to challenge the player for a better score.

Planet U

Planet U is the alien planet featured in Rock Raiders. The entire plot takes place on this planet. Planet U is located in another galaxy, outside of the Milky Way. The rock below the planet's surface is abundant with Lego ore and energy crystals. Monsters made out of rock, ice, and lava live in caverns deep underground, feeding on the energy crystals. Other creatures like giant slugs, scorpions, and spiders also make their homes in the tunnels. Runs found in one of the books suggests an intelligent civilization may have once lived on the planet. Planet U has very little oxygen, the Rock Raiders must build Support Stations to purify the air, and make it breathable.

Vehicles

Rock Raider HQ is made up of a number of buildings. Buildings must be constructed by power paths, which can be used to link buildings together to allow power to flow to them all. Rock Raiders can run much faster on power paths than rubble or cavern floor, and power paths can also be used as dams to temporarily block lava erosion.
The Ultimate Lego Book contained concept art for Lego Rock Raiders on pages 30–31, showing how the theme developed over time. The original plans were vastly different:
