Aliens

Aliens are the main antagonist of Out of Space. They are characterized by their striking purple color and ability to quickly take over rooms, if left unchecked.

Behavior

At the start of the game, most of the Spaceship will be covered in goo. Players that walk on goo become increasingly dirty, which makes entering an infested room a laborious process. While goo mostly can't spread on its own (except via a Vent or depowered Battery Slot), it has a chance to generate Cysts over time.

Cysts may spawn on the floor and on doors. Each cyst increases at a rate of once every ? seconds, eventually popping up and releasing an Alien after increasing twice.

Finally, there are Aliens. By moving around the environment, Aliens can cover clean surfaces with goo, perpetuating the process of spread throughout the ship. Aliens may also:

• Spawn Cysts on doors, possibly creating a breach into an otherwise clean room;
• Infect Furniture, deactivating it and preventing its usage;
• Turn into Purple Cysts, starting a process of Metamorphosis and possibly mutating into an Advanced Alien.

Cleaning

Goo can be cleaned in multiples ways, such as with Mops, Buckets and with the help from a Cleaner Bot. Conversely, Cysts can only be cleaned with Buckets, making them particularly tricky to clean.

Aliens must be first stunned with a Mop, Bucket or with a Dog's bark and then either 1. be stored on a table or a refrigerator, or 2. be consumed via Recycler, Macrowave, Mixer or by throwing it in space.

Advanced Aliens

3-4 Mutations are secretly and randomly selected at the beginning of a run. If an Alien is allowed to mutate, it may take the form of any of these previously selected mutations.

The entire mutation list is available below.
