Mission Briefing: Our scanners have picked up possible Imperial signals around the base. Move out and investigate. Eliminate any potential threats before they can alert the Empire to our presence. We cannot afford to be found out.
The tutorial begins with you as an armed soldier of the Rebel Forces on patrol in the snow. You are basically following a well-marked patrol route. Along the way you will encounter Imperial Droids that you need to shoot with your blaster.
The blaster has a scope that you can scan with - and the patrol route is helpfully marked by flagged spots.
As you progress you are introduced to the Weapon Cards, and basic commands like Sprint, Aim, and Fire. When you get an Ion Grenade (card) you are prompted to use that to destroy the next droid.
Your final lesson has you picking up a new weapon - a rocked launcher - and using that to take out the next (last) droid! Doing so completes the tutorial and unlocks the Achievement: Do... or do not. There is no try (15g) Complete the Tutorial.
You can replay the Tutorial if you want to go for a better time - or you want to practice with the different weapons that are part of it - or you can end it and go to the Play Screen.
