EVA stands for Extra Vehicular Activity; this refers to any situation in which you are in space. Space can be very dangerous if you are not prepared, and there are many ways to go about venturing into it. For the purposes of this guide, EVA will also include depressurized environments within the station. Please be aware that EVA is often used to refer to EVA storage, which is where supplies for EVA can be found.


Internals, which is short for "Internal Atmosphere," are required to keep you breathing in rooms without oxygen. Keep in mind that they may also be used to prevent you from breathing harmful gasses, such as phoron, but will not protect you from lethal pressure (or lack thereof). Most often, internals includes a breath mask and an oxygen tank. You start with these supplies by default, and they are located inside of a box in your backpack. You can turn them on using this button: Internals.gif

Space Suits

Space suits, which come in three main varieties, are required to survive in an under pressured or over pressure environment.

Type Image Description
Softsuit Softsuit.png Softsuits are the least advanced type of space suit. However, they can be worn by all crew members, regardless of species, and are commonly available. The drawback is that they can be torn very easily. They are not intended to be used outside of emergencies.
Voidsuit Voidsuit.png Voidsuits are the most commonly used suit. Although it is only wearable by humans by default, they can be fitted to any other species, besides Vox, using a suit cycler. These are more durable than softsuits, and often come with protection related to the job they are designed for.
Hardsuit Hardsuit.gif Rescue hardsuit.gif Hardsuits, often known as RIG suits, are the most advanced variety of space suit. They allow heavy customization and are often specialized for the job they were designed for, but they are harder to operate and often hard to gain access to. Certain varieties are also only able to be operated by one species, usually Humans.

Mechs can also serve as EVA capable vehicles. The Hoverpod especially, since it has thrusters.


As there is no flooring to walk on in space, you must use one of the following methods to move.

  1. Move adjacent to a structure. While next to a solid object such as a wall or window, you can move normally at a decreased speed and with a chance to slip (which can be removed with Mashoe.png magboots). This is a bit dangerous since you might slip and end up floating in space. In that case, use one of the other methods to return or call for help.
  2. Use a jet pack. Right click it and turn it on before use. If it is on you can move freely trough the space.
  3. Use a fire extinguisher. All you have to do is use it in the opposite direction you want to go. Due to its limited storage and imprecise aiming, the jet pack is better than the extinguisher.
  4. Throw items. Trowing objects in the opposite direction of where you want to achieve the same result as with the extinguisher. However, you are limited to the number of objects you have, which makes this more of a survival tactic then the desired way to move in space.

Be careful, moving too far into space and you may be lost forever.
