In Terror Below, your objective is to be the first to score 20 Victory Points. Depending on the Vehicle you play against a Worm, you will have a certain number of Actions to perform: divert its attention, move around the game board, pick up rubble to exchange it for Weapons or Survival Items, pick up a Worm Egg to deliver it, then fight. If your character dies, recruit another one, but be careful because you will only have 3 at the start!
