We'll keep this short, because our resident Star Wars and RPG fiend, Ewan, has leapt on this (ahem) Star Wars RPG with a vengeance - hich means we should be seeing a full review within a matter of days.

WPC has the scoop on this one:

The game has finally launched on Microsoft platforms today, opening up the popular, fictional galaxy far, far away. Windows Phone has received a mixture of Star Wars games, some containing angry birds and others tasking players to build tower defenses.

Star Wars: Assault Team is a card come strategy, turn-based game. Players are able to collect and assemble a powerful team of heroes to battle enemies and even other players across the universe. 

For all the movie and lore buffs out there, Star Wars: Assault Team takes place between A New Hope and Empire Strikes Back. But just because this is a card game, don't be fooled to believe it'll either be too simple or boring to play through. There's a lot of content here.

It's available in the main Windows Phone Store, of course, at least it is if your device has 1GB of RAM (or more):

• Infiltrate enemy fleets and outsmart your opponents in exciting, face-to-face combat. Embark on epic missions to escape from enemy ships, find the Wookiee resistance, survive ambushes on the streets of Mos Espa, and much more! Fight for ultimate control of the galaxy in this strategic combat game, where every move counts!
• BUILD YOUR VERY OWN ASSAULT TEAM - Collect and play with your favorite classic Star Wars characters such as Luke Skywalker, Han Solo, Boba Fett, Tusken Raiders, and more! Each hero has unique stats, abilities, and attacks to increase your team’s overall strength.
• COMPELLING BATTLES - Take your assault team into battle, and defeat galactic enemies and other players! Strategically choose your squad, then deploy your team members’ special tactics. Crush your opponents to earn valuable rewards and new characters!
• LEVEL UP YOUR HEROES - Collect items to train your characters and improve their special attacks, making your team even more dominant against increasingly powerful enemies!
• EXCITING COMPETITIVE PLAY - Fight against other players in PvP battles to win extra loot! 
• STUNNING GRAPHICS - Experience cinematic, high-quality graphics on your mobile device as you make your way from scene to scene with full character and background animations during combat.

The cross-platform trailer will give you an idea of what to expect - the power-ups are presumably where the developers make their money, through in-app-purchases (IAPs):

As I say, watch for a full review very, very shortly.
