Jones

The Nostromo's unofficial mascot, Jones the cat can be both helpful and bothersome to both opposing sides during the game.

For the Alien player, his Jones card is used as a Mystery Marker on the layout, confusing the Crew player and possibly leading his crewmembers in unfortunate directions.

If found by the crew, Jones may be captured, preventing the Alien player from using him any further. However, the cat can be obnoxiously hard to catch:

A crewmember carrying Jones without the Catbox may carry no other Equipment. If Jones is alive at the end of a game that the crew have won, that player gets one extra victory point. Jones may not be killed by the Alien, the Robot, or a crewmember - he may only be killed by being ejected, or by being caught in the Nostromo's detonation.
 * 1) When the Crew player draws his Jones card, he places it face-up near his discard pile.
 * 2) Upon encountering the Alien's Jones card on the layout, a crewmember present may act to pick up Jones (either with the Catbox or without) - but only if his own Jones card is on the table.
 * 3) The Crew's Jones card then replaces the Alien's on the layout (place him either under the crewmember carrying him, like a piece of Equipment, or within the Catbox). The Alien player's copy of the card is discarded and becomes a dud.
 * 4) If on one of the Alien player's future turns Jones is no longer carried by a Crewmember (and is not in the Catbox), the alien player may replace the Crew player's Jones with his own from his hand, turning it into a face-down Mystery Marker once again, and may move it as normal. The Crew's copy of the card is discarded.
