Can the empire win the tutorial against 2 rebels heroes if only 2 people are playing the game? That way you only get 1 group of stormtroopers and an officer. I was up against the wookiee and the marksman. It didn't go well.

Is enough to easily win, just let the heroes open a door, and go for both terminals, if they open the door in round 1 (they usually do), you win in round 2 with the storm trooper on left terminal.

What is the objective of the mission? It showed me how to set it up, but as far as objectives I didn't see anything. I just assumed it was a slug-fest, which ended badly for the imps.

Rebels have to wipe out all of the Imperials, and the Imperial player has to either defeat 1 hero or interact with the terminal.

Under "Ending a Mission" on page 7 of the Learn to Play guide.

according to the FAQ the imperial player now has to activate both terminals, which in my opinion makes it very, very hard to win as empire, even more so against two players. (Remember: they don't get Heroic or Legendary reward cards during the tutorial)

“For the Tutorial, the Rebel players’ objective is to defeat all Imperial figures.

The Imperial player’s objective is to either have his figures interact with both terminals or defeat a hero.”

I completely missed the FAQ bit, so thanks for the catch.

When we did it I had no issue just focus firing one hero down. Win or loose it doesn't really matter anyways. I'd run it a couple times. Its quick and you can learn the rules before doing something that will affect the campaign.
