Outpost 13

Outpost 13 is a point-and-click action-adventure game set at an outpost on Achelous IV. You play as Fen, a dog who comes into contact with an alien biological agent and bonds with an alien life form called Tantalus. Your objective is to make the stationed crew abandon its five-year mission and leave the planet early, so you can reach the nearest spaceport. There may be higher powers at play.

Achelous IV

Achelous IV is a life-viable planet several times larger than Earth. Its winters and summers each last several years, and the story takes place 13 Earth months into winter.

Stay undercover

You take the role of an alien monster while maintaining your cover as Fen, the crew's pet dog. You strategically kill crew members and try to create enough fear for them to abandon the outpost.

To separate and alienate crew members, you can create distractions, use the ventilation system and temporarily cut the outpost's power. If you fail to stay hidden and the crew discovers you as the monster, they respond with flamethrowers, which can destroy you with fire.
