One of the easiest achievements if you ask me.
As others have stated, after the cut scene where Darth Vader tells two Death Star workers to follow him, you'll be placed in a trench like enviroment.
This is the part where the achievement is referencing to. Whatever you do, don't press the fire button. Just strafe left and right; whilst moving forward.
You don't even need the Red Brick for invincibility.
I died once whilst strafing from the bullets and got this achievement.
Won't take you long, only took me 10 seconds at least :)
