7649 MT-201 Ultra-Drill Walker is a Mars Mission set released in 2008. It includes the Ultra-Drill Walker with removable cockpit, and an alien starfighter. Also included are two minifigures.


The Ultra-Drill Walker features a large drill mounted on the top, with a blunt shooter for defense. The cockpit can be removed, allowing the drill to point down, as it would when drilling for Energy Crystals. The drill can be turned with a small gear on the side. The cockpit also features a small vehicle which can come out of the back, though there are not enough minifigures included in the set to have all the vehicles driven at once.

The alien ship is black and green, and has four "lasers" on it for combat, though these have no function in the set. It has room for an included Alien Commander. Description This is a description taken from Please do not modify it. (visit this item's product page)

Change modes and stomp into battle!

This powerful drilling rig may look like a simple base for mining energy crystals, but it's so much more -- when hostile aliens attack, the MT-201 Ultra Drill Walker converts into a massive 4-legged mobile tank-mech and thunders across the surface of Mars!

  • Includes 2 astronaut minifigures and alien commander!
  • Detach the high-tech observation shuttle to keep an eye out for the Alien *Commander and his strike ship!
  • Launch the missile at the alien attack ship!
  • Turn the gear to spin the drill for mining energy crystals!
