Chestburster

When a game of ALIEN begins, the alien Chestburster is hiding far away from the crew, in a corridor on C-Deck. Unable to take any actions at all, the Chestburster is extremely vulnerable during this period - it can only move, most likely doing so in the opposite direction of the Nostromo's human crew. If the crew are able to stun and capture the Chestburster (with the use of a Shock Tube and Net, respectively), they stand a very real chance of bringing it to the Main Airlock and ejecting it from the ship, thereby winning the game without losing another crewmember.

Stunned
If, as the Alien player, your Chestburster is stunned at the beginning of your turn, roll one die. If the number rolled is less than the number of consecutive turns that your Chestburster has been stunned (including the current one), the Chestburster has awakened, and, using its body acids, has freed itself from the Net - the Chestburster may move freely as normal.

Growth
The Chestburster may not become the Alien while face-up on the table. When it does become the Alien, keep the Chestburster card in play as a decoy Mystery Marker until it is revealed (essentially serving as the 'shed skin' that Brett found on C-deck). After this occurs, treat the card as a dud.
