How to unlock the Trial by Fire achievement in Pinball FX3 - Definitive Guide
Once that's been taken care of, you'll have the flamethrower. You'll need to make sure you have at least 6 ammo showing on the ammo display at the bottom right of your screen. If not, you can gain ammo by hitting the ammo target 4 times.
Then wait for the Alien to appear, and shoot the flashing white target. Then instead of shooting the locker to hide, fire the ball up either orbit to light him up.
Good luck. :)
NOTE: You will start the game with a pistol. Starting main missions will upgrade your weapons. After 2 missions, you will acquire the shotgun. After 4 missions, you will have access to the Flamethrower. Keep in mind you do not need to beat or win the missions - simply starting them grants you access to the weapons mentioned above. You will also need at least 6 ammo to use the flamethrower. You can get more ammo or refill ammo by shooting the Ammo target on the left of the playfield.
Step 1: Play through any 4 missions to Acquire the Flamethrower
Shoot the Mission Computer a couple of times to start a mission. Play through any mission and either beat it or fail (it doesn't matter.) Repeat this 4 times.
Step 2: Wait for the Alien
Make sure you have the flamethrower and at least 6 ammo. (If you need ammo, then shoot the ammo target on the left to refill your ammo.) Once you have the flamethrower and necessary ammo, hold your ball, wait and listen for the alien to growl. You will also see "THE ALIEN IS NEARBY BE CAUTIOUS!" on the DMD (Dot Matrix Display)
Step 3: Use the flamethrower on the alien
Shoot the ramp on the right, it will light the flamethrower lights in both the right and left orbit. Now shoot either the right or left orbit to fire the flamethrower. She will use it on the alien and you will have earned the trophy.
