What We Think Fun Factor: Durability: (what this means) The Good: Durable building system encourages imaginative play The Bad: Lots of small parts to keep track of In a Nutshell: The Mega Rig Space Shuttle Mission Set provides hours of fun constructing space vehicles and thinking up places to explore At a Glance Ages: 4 and up

The UFO included in this set features other-worldly lights and sound, and it is powered by three button-cell batteries (AG13/LR44). Test batteries are included, but you will want to purchase another set just in case. The Shuttle Mission Set is compatible with all Mega Rig building systems, making it easy to combine different sets and inspire kid's creativity.

Galactic Exploration
Once a spaceship has been assembled, there are plenty of missions your child can accomplish. Between launching the satellite into orbit and coordinating an exploratory space walk, your child will be busy watching out for missiles shot from the UFO with its alien inside. The durable octagon shaped connectors hold pieces of each space craft together until they are pulled apart on purpose.

Our favorite configurations included snapping the bright orange all-terrain wheels onto the shuttle or UFO for land adventures, combining the shuttle and the fuel cell into one gigantic space ship, and loading the launch pad with accessories to create a headquarters for operations on distant moons and planets.

Other cool features include a space arm controlled by a lever, an oversized astro grabber for moving equipment or keeping the alien at bay, and plenty of fun compartments for the astronaut and alien to hide in. Your child will surely want to take this shuttle everywhere, but with so many small parts to keep track of, traveling with this set can require extra attention to detail.

Long-Lasting Imaginative Play
The sturdy plastic shuttle and its accessories held up well throughout our vigorous test missions, and the Mega Rig building systems are known for their durability. The moving parts and hinged compartments that make this shuttle so much fun could potentially come apart with lots of rough play, but we found the system to be extremely durable.

With the alien and the astronaut ready to be your friend or enemy, and the ability to make more than one vehicle at the same time, this building system is great for cooperative play or a single child with an active imagination. The ability to combine and recombine parts in so many ways offers a new experience every time your child picks up a piece of this shuttle system, so the fun never runs out.
