## Description

Used in conjunction with a [Hardsuit Helmet](/wiki/hardsuit-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 [Hardsuit Backpack](/wiki/hardsuit-backpack) for extra storage, or a [Hardsuit Jetpack](/wiki/hardsuit-jetpack) for additional storage and jumpjet capabilities.

The [Hardsuit](/wiki/hardsuit) has more armor than the [EVA Suit](/wiki/eva-suit), features one extra [Filter](/wiki/filter) slot and the ability to accept [Integrated Circuit (IC10)](/wiki/integrated-circuit-ic10) chips.  It is however much more expensive to produce due to the extreme conditions that it can survive under.

## Usage

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](/wiki/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 suit's slots and its various settings.  These only function when wearing a suitable closed helmet, and are as follows:
- **A/C On / Off**  (Temperature control on/off)
- **Filters On / Off** (Filter
- **Air On / Off**
- **Pressure Up / Down**  (with a range of 0kPA to 202kPa, or 0-2 Earth atmospheres)
- **Temperature Up / Down**  (with a range of 0°C to 60°C)

Your suit [Battery](/wiki/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](/wiki/duct-tape) in your right hand and holding the right mouse button.  The colour of an (unworn) suit can be changed using [Spray Paint](/wiki/spray-paint).

If the helmet is open while the air release in on, air is wasted.

## Slots

Contains 8 slots:
- 1x **Air Tank** - Insert a [Canister](/wiki/canister) or [Gas Canister (Smart)](/wiki/gas-canister-smart) with a breathable gas mix (for example [O2](/wiki/oxygen), [Air](/wiki/air), [Air 20/80](/wiki/air-2080) or [Nitrox 35/65](/wiki/nitrox-3565))
- 1x **Waste Tank** - Insert an empty [Canister](/wiki/canister) or [Gas Canister (Smart)](/wiki/gas-canister-smart) where gases removed by the [Filter](/wiki/filter)s will be stored
- 1x **Life Support** - Insert a charged [Battery Cell](/wiki/battery-cell) (ideally Large or Nuclear)
- 1x **Processor** - Optionally allowing for a programmed [Integrated Circuit (IC10)](/wiki/integrated-circuit-ic10)
- 4x **[Filter](/wiki/filter)s** - Insert at least one [CO2](/wiki/carbon-dioxide) Filters (if Human), plus others depending on your breathable gas mix (usually [Nitrogen](/wiki/n2))

## Notes

- As noted on [Venus#Real Venus](/wiki/venus#real-venus), the hardsuit can survive at true Venus pressures, the Waste tank does not fill any faster at those pressures.
- Suit pressure set to 50-100 KPa (0.5 to 1 Earth atmospheres), Humans in-game tolerating 11 to ~250kPa and surviving 11 to ~300kPA)
- Suit temperature is normally set to 18-21°C, Humans in-game preferring 10-29°C, tolerating 0-39°C and surviving around -10 to 49°C
- Its has better a thermal insulation (convection and radiation) as the regular [EVA Suit](/wiki/eva-suit).
- Additional key bindings to control your suit functions can be set in the Game Settings ---> Controls.

- The maximum allowed pressure the filters can cope with in the Waste Tank is 4052kPa (well 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](/wiki/carbon-dioxide) 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](/wiki/oxygen) + 75% [Nitrogen](/wiki/nitrogen) into your tank, the Nitrogen would accumulate in your suit/helmet over time and suffocate you unless you have a [Nitrogen](/wiki/n2) 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](/wiki/space-helmet)

- It is theoretically possible to mix [EVA Suit](/wiki/eva-suit) elements and [Hardsuit](/wiki/hardsuit) elements, although this is relatively uncommon
- Damaged suits can be recycled (assuming you have a new one to use!)
- Equipping an [Integrated Circuit (IC10)](/wiki/integrated-circuit-ic10) in the designated slot has a constant power draw of 5 watts from the suit battery.
- Writing to the Error parameter with an [Integrated Circuit (IC10)](/wiki/integrated-circuit-ic10) creates an audible sound, this could be used for custom alerts.

## Integrated Circuit

The Hardsuit is uniquely capable of accepting an [Integrated Ciruit (IC10)](/wiki/integrated-circuit-ic10).  Within a Hardsuit, this IC cannot toggle itself off and will run as long as there is battery power in the suit, until the IC is removed.

## Automation

Some ideas for automating the suit using an [Integrated Circuit (IC10)](/wiki/integrated-circuit-ic10) include
- Closing the helmet in a hostile atmosphere
- Locking the helmet in a hostile atmosphere
- Unlocking the helmet in a good atmosphere
- Deactivating airflow, filtration, and AC when helmet is open and in a good atmosphere , and reactivating them when helmet is closed.
- Only activating filtration when CO2 levels are too high. This can greatly increase the lifetime of the filters, and reduces power use.
