Oxygen Suit

Four-piece armour that doubles as personal life support on airless worlds. Two tiers, plus two Tier-2-class hazard variants for the extreme worlds.

Overview#

Wearing the full set (all four pieces) keeps you breathing off-world by draining a finite air tank instead of suffocating. The tank refills instantly in any breathable zone (oxygen field, terraformed ground, launch-pad safe zone) — and, since the suit-and-station integration, also at airlocks (below).

Every full suit (Tier 1, Tier 2, Thermal or Cryo) holds 900 air. Without a suit you have only 300 air (your own lungs). A mixed set still works as life support. Any missing piece = no life support.

Drain: with a full suit you lose 3 air per check (every 10 ticks). With no suit you lose 30 air per check. An unshielded hazard (below) multiplies drain by 4.

Hazard variants — Thermal & Cryo Suits#

Cindara (and Nyxara's Dayside) is hot; Glacira, Mars (and Nyxara's Nightside) are cold: unprotected, the planetary hazard makes your suit work overtime — oxygen drains at 4× the normal rate (there's no separate damage; running dry is still the danger).

Cold comes in two strengths. Mars is cold but not frigid: any full set of Tier 2 class pieces (Tier 2, Thermal or Cryo, even mixed) keeps its cold out, so a Tier 1 suit is the only one that struggles there. Glacira, the Martian Polar Cap and Nyxara's Nightside are frigid: only a full Cryo Suit (or, on Nyxara, a flaring Dawnband Stone within four blocks) keeps that cold out. The HUD badge warns with a red HEAT! / COLD! while you're exposed, with ember puffs (Cindara) or a creeping frost vignette (Glacira) as feedback.

The shield engages only when all four pieces match the hazard; the HUD badge then shows SUIT HEAT / SUIT COLD and oxygen drains at the normal 1× rate. Mixing variant pieces with other pieces keeps life support — you just lose the heat and frigid-cold shield (a mix of Tier 2 class pieces still keeps Mars' milder cold out).

Rad Lining (radiation)#

Mars dust storms and Nyxara's Dayside and Nightside are irradiated. Without protection, radiation makes your suit drain at 4× and, from radiation level 2 upwards, hurts you while you stand outside a sealed oxygen field: one point of damage every two seconds at level 2 (a dust storm, the Dayside), two at level 3 (the Nightside, or the Dayside during a flare). The Moon and the orbital station never need it.

The Rad Lining is an upgrade, not a new suit. Craft a Rad Lining from Regolith, Raw Hematite and a Titanium Ingot, then combine it at a smithing table with a Tier 2, Thermal or Cryo suit piece and one Titanium Ingot. The piece keeps its name, tier and hazard shield, and gains a gold Rad-Lined line. The shield engages when all four worn pieces are lined; the HUD then shows RAD LINING.

Where several hazards meet, you need every matching protection: the Nyxara Nightside is irradiated and cold (a Rad-Lined Cryo Suit, or Rad Lining beside a flaring Dawnband Stone), the Dayside irradiated and hot (a Rad-Lined Thermal Suit), and Mars in a dust storm is irradiated and cold (any Rad-Lined Tier 2 suit; a Rad-Lined Cryo Suit on the Polar Cap). The HUD warns about the hazard that would hurt you next.

Progression note#

Cindrite (Thermal) is mined on Cindara itself, so the usual loop is: dash in a plain Tier 2 suit, mine your first cindrite, then craft the Thermal Suit for serious expeditions. The same applies to glacite and the Cryo Suit on Glacira.

Airlock refill#

Within 4 blocks of a Gas Tank or Oxygen Generator holding Oxygen, a worn suit refills from that store. Every suit gets 90 air per check (every 10 ticks). Each air unit costs 2 mB of oxygen (scaled by fuelCostMultiplier). A Gas Tank at the base entrance therefore acts as an airlock: step inside, top up, head back out. The Creative Gas Tank works too.

Obtaining#

Tier 1 (shaped, nerosteel): helmet NNN / NGN (G = Glass visor), chestplate N N / NCN / NNN (C = Rocket Fuel Canister life-support core), leggings and boots all-nerosteel.

Tier 2 (shaped): each Tier 1 piece surrounded by 4 Cindrite —

. C .
C P C
. C .

P = the matching Tier 1 piece · C = Cindrite

Cindrite only mines on Cindara (Tier 3 rocket, itself gated on Station Wall), so the Tier 2 suit sits at the same progression depth as the Tier 3 rocket.
