The Empire commonly uses these speeder bikes for scouting and reconnaissance missions, but they can also be deployed to terrifying effect on the battlefield, where their sheer speed often prevents the enemy from taking a clean shot.

The 74-Z Speeder Bikes Unit Expansion includes a unit of two 74-Z Speeder Bikes, and all the unit cards and upgrade cards you need to expand your forces with these lightning-fast speeders. 

• This expansion contains two highly detailed, unique 74-Z Speeder Bike miniatures, inviting your Imperial Scout Troopers to zip across the battlefield at blazing fast speeds. The squad leader miniature is unique to this expansion pack, while the other miniature is a duplicate of a 74-Speeder Bike miniature in the Core Set.

This is not a complete game experience.  This is an expansion.
