LEGO MT-201 Ultra-Drill Walker 7649

All about this set

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 an 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!
