Go into the armory and grab a weapon.

From Create Your Own Story

Though the armory is a bit of a walk away, you make your way there. You blast a few more crabs on the way, just because. In fact, by the time you actually reach the armory, you feel like quite the badass. Walking inside, you can't wait to see what kind of huge guns it contains.

You discover that the ship's armory is much larger than you remember, and you remember it being quite large. You pick out the biggest gun you can find (though you aren't quite sure what it does) and start to walk out. Unfortunately for you, the door to the armory has sealed, and it is just finishing its jettison sequence. Who could have guessed that it would actually launch after the locks were released? You are pressed against the ceiling as the room drops away from the ship. The military grade hardware survives the incredible heat and pressure from entering the planet's atmosphere. You, however, are burned, then crushed flat to the ceiling.

CONGRATULATIONS! YOU HAVE BECOME THE ARMORY'S NEW DECORATION!
