> *"The Hardsuit Helmet is similar to the [Space Helmet](/wiki/space-helmet), but can withstand higher temperatures and pressures. It's perfect for enduring harsh environments like Venus and Vulcan."*

## Description

Paired with a [Hardsuit](/wiki/hardsuit), it provides a contained, portable, pressurized, breathable environment need for protection against the vacuum of space.

The [Hardsuit Helmet](/wiki/hardsuit-helmet) has more armor than the [Space Helmet](/wiki/space-helmet), and a slightly more powerful light.

## Usage

Your helmet must be worn with a suitable suit to function properly.  Your helmet functions can be accessed by pressing the Number **'1**' key.  This will bring up a panel showing the helmet's settings, as follows:
- **Open / Close Helmet** - Open and close the glass visor of the helmet, venting or enclosing your suit atmosphere  *(Keyboard shortcut - I)*
- **Lock/Unlock Helmet** - Allow or prevent the opening of the visor (useful to avoid accidental opening)
- **Light On / Off** - Toggle the helmet's forward facing light on and off  *(Keyboard shortcut - L)*
- **Flush** - Expels helmet's (and suit's) current atmosphere and replenishes from the air tank.

The helmet's light draws power from your suit [Battery](/wiki/battery-cell). If damaged, your helmet 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) helmet can be changed using [Spray Paint](/wiki/spray-paint).

## Notes

- **Caution:** An open helmet allows exposure to the conditions outside of the suit.
- If you open the helmet in a contaminated, external environment (and lack [Filter](/wiki/filter)s to process the contaminants), **Flush** the helmet.
- It is theoretically possible to mix [EVA Suit](/wiki/eva-suit) elements and [Hardsuit](/wiki/hardsuit) elements, although this is relatively uncommon.
- Damaged helmets can be recycled (assuming you have a new one to use!)
- The helmet light uses 100 watts of power when on, For comparison most [wall mounted lights](/wiki/kit-lights) use 50 watts.
