Used in conjunction with a Space Helmet to go outside a pressurized and breathable environment. It features adjustable pressure and air conditioning (temperature) settings, as well as an warning system that will alert the occupant should the atmosphere inside the suit become hazardous. It can also carry a Spacepack for additional storage and jumpjet capabilities.

The EVA Suit is the lightest of the two available suits being the Hardsuit.


Your suit must be worn with a suitable helmet to function properly. You must insert suitable gas canisters and filters into the suit's slot (see below). These will need to be manually changed on a periodic basis, although the canisters can also be recharged/drained using a fully-supplied Suit Storage rack.

Your suit readouts are normally displayed at the top-right of the screen. Your suit functions can be accessed by pressing the Number '3' key. This will bring up a panel showing the slots and their various settings. These only function when wearing a suitable closed helmet, and are as follows:

  • A/C On/Off (i.e. Temperature control on/off)
  • Filters On/Off
  • Air On/Off
  • Pressure Up/Down (with a range of 0kPA~202kPa, or 0~2 Earth atmospheres)
  • Temperature Up/Down (with a range of 0°C~60°C)

Your suit Battery will also power (and be drained by) the light in any attached helmet. If damaged, your suit can be patched by holding Duct Tape in your right hand and holding the right mouse button. The colour of an (unworn) suit can be changed using Spray Paint.


Contains 6 slots:

Resource consumption[edit]


  • Oxygen consumption by difficulties
    • Easy (OxygenRate 1): 0.82 mol/minute ± 4%
    • Normal (OxygenRate 2): 1.05 mol/minute ± 4.5%
    • Stationeer (OxygenRate 4): 3.41 mol/minute ± 1.5%

Actual Formula: 0.0048 mole pr tick (x 1.5 x difficulty multiplier)


  • Suit pressure set to 50-100 KPa (0.5 to 1 Earth's atmosphere), Humans in-game tolerating 11~250kPa and surviving 11~300kPA)
  • Suit temperature is set by default to range between 18~21°C, Humans in-game preferring 10~29°C, tolerating 0~39°C and surviving around -10~49°C
  • Additional key bindings to control your suit functions can be set in the Game Settings ---> Controls.
  • The maximum allowed pressure inside the filters can cope with in the Waste Tank is 4052kPa (below its maximum pressure). Low/critical Oxygen warnings will occur close to this value as your filters cease to function.
  • The default filter is the CO2 filter, a gas generated by the Human character when consuming breathable gas.
  • Make sure if you aren't using 100% Oxygen in your breathing gas that you add additional Filters! E.g. if you put the common "Air" mixture of 25% Oxygen + 75% Nitrogen into your tank, the Nitrogen would accumulate in your suit/helmet over time and suffocate you unless you have a Nitrogen filter to remove this.
  • If you have the correct filters and breathable gas but are still experiencing problems, refer to the "Flush" function on your Space Helmet
  • It is theoretically possible to mix EVA Suit elements and Hardsuit elements, although this is relatively uncommon.
  • Damaged suits can be recycled assuming you have another one.

Additional Explanation of Breathing inside a Suit[edit]

Think of it this way: You start with a 100% Oxygen atmosphere in your suit/helmet. Through breathing you will replace some of the O2 with CO2. The CO2 will be removed by the suit's filters (which are by default three CO2 filters), in turn dropping the pressure in the suit/helmet. The breathing tank will replenish the suit's pressure atmosphere (with whatever is in the breathing tank) until the target pressure of the suit is reached again. This cycle will repeat over and over. So if you have anything else than pure O2 in your breathing tank, it will be introduced into the atmosphere of your suit and will accumulate over time (ultimately to 100%, because you're not breathing it and it doesn't get filtered out!) If you don't have pure Oxygen available or choose not to use it, you can use other gas mixtures, but must be sure that you add the appropriate filters to your suit as well.
