Signs of Life Armor Guide: Best Sets and Progressions

Armour is the quiet half of Signs of Life's combat progression. Weapons get the attention; armour decides whether you survive the first mistake. The official wiki lists 231 armour entries, from copper plates to energy force fields, but it does not publish defence numbers. That makes set identity more useful than a stat table.

This guide covers the sets, their bonuses, the progression path and the loadouts that work in caves, boss fights and co-op.

Complete sets matter more than single pieces.

How armour works

Armour is crafted, not looted. You mine the ore, process it and build the set at the workbench chain. Each set has a material identity and, for some sets, a special effect.

The wiki pages describe the sets rather than their numbers. The practical differences come from:

• The material tier (copper, bronze, iron, steel, alien).
• The set bonus.
• The weight and mobility trade-off.
• The environment you are entering.

Do not assume a higher-tier set is always better. A mining suit is better in a mine than a combat set, and Ghost Hide's reflect can outperform raw defence in a long fight.

The sets

Copper and bronze

The first craftable sets. They teach the armour chain and provide enough protection for the surface and shallow caves. Do not over-invest; you will replace them quickly.

Bone

A cheap early-mid set made from bone. It is a bridge between metal tiers and a reasonable choice if you are short on ore.

Bornite

A mid-game metal set. Bornite is one of the ore tiers, and the set is a reliable upgrade for players entering the deeper caves.

Ghost Hide

Ghost Hide is the first set with a memorable bonus: it reflects two damage back at attackers. That makes it excellent against fast, multi-hit enemies and surprisingly good in co-op, where the reflect adds up.

Use it when:

• You are fighting many small enemies.
• You expect to be hit often.
• You want a defensive set without giving up mobility.

Do not use it as your boss set unless the boss hits rapidly and lightly. A 50-damage mech punch is not a reflect fight.

Energy Plate

Energy Plate provides a low-tier force field that recharges over time. It rewards disengaging: take a hit, break line of sight, let the field recover, re-engage.

Use it when:

• You are exploring a dangerous zone with cover.
• You are learning a boss pattern and need a buffer.
• You play co-op and can rotate aggro.

Steel Combat

The reliable late-mid combat set. Steel Combat is the general-purpose pick for caves, ruins and most boss attempts until you have alien materials.

Hephaestus Mining Suit and Mining Suit Mk2

The mining suits are tools as much as armour. They support the mining loop and the Hephaestus/Prototype suit progression. In 1.0, the Prototype Mining Suit is no longer handed to you openly; it is hidden in the world, with a datapad in Dr. Hahn's lab pointing the way.

Use mining suits for:

• Ore runs.
• Cave exploration.
• Long sessions where inventory and mining speed matter.

Do not wear them to a boss fight unless you have no alternative.

Alien and late-game sets

Xenohide and Xenoid Alloy feed the late-game armour line. These sets are the payoff for exploring Xenoid territory and are the best general-purpose gear for the finale.

The Xenoid guide→ covers where the materials drop.

The progression path

Early game

1. Craft copper or bronze pieces as you find ore.
2. Complete the set before chasing a new tier.
3. Keep a bone set as a cheap backup.
4. Do not sell hide or bone; both feed later recipes.

Mid game

1. Move to bornite or steel as your main set.
2. Build Ghost Hide if you fight packs.
3. Build Energy Plate if you are learning bosses.
4. Upgrade the workbench chain alongside the armour.

Late game

1. Craft the alien set from Xenohide and Xenoid Alloy.
2. Keep a mining suit for resource runs.
3. Keep a Ghost Hide or Energy Plate set for specific fights.
4. Upgrade cybernetics and utility gear.

Armour and cybernetics

1.0 supports cybernetic implants such as the Cybernetic Eyes (Laser) and Cybernetic Stomach (Regurgitator), and it fixed Optical Camouflage so it works with implanted mechanical arms and legs.

These are equipment choices, not armour sets, but they change how you build a character. The laser eyes give you a built-in weapon; the regurgitator gives you a utility option. Test them before a boss fight, not during one.

Best armour by role

Best general set

Steel Combat for the mid-game, the alien set for the late game. Reliable, repairable and appropriate for most content.

Best defensive set

Energy Plate if you can disengage; Ghost Hide if you expect many small hits.

Best mining set

Hephaestus Mining Suit or Mining Suit Mk2. The mining bonuses matter more than the defence.

Best co-op set

Ghost Hide or Energy Plate. Both reward the rotate-and-recover rhythm of a two-player fight.

Best boss set

The alien set if you have it; Steel Combat if you do not. Do not bring a mining suit.

Co-op armour roles

In co-op, armour is a role signal:

• The player in heavy armour holds aggro.
• The player in lighter armour flanks and revives.
• Both players should carry a backup set if the world allows it.

Do not both wear the same glass-cannon setup. One mistake ends the attempt.

Common armour mistakes

Crafting one piece of a late set. Finish the set you have before starting a new tier.

Wearing a mining suit to a fight. The stats are wrong for combat.

Ignoring set bonuses. Ghost Hide and Energy Plate are defined by their effects.

Selling hide and bone. Both feed mid and late recipes.

Skipping repairs. A broken set is worse than a lower-tier set.

Which armour should you craft first?

Complete the copper or bronze set, then move to steel. Build Ghost Hide or Energy Plate as a specialist set, and save alien materials for the late-game set. The weapons guide→ covers the offensive side, and the bosses guide→ covers the fights where armour matters most.

FAQ

What is the best armor in Signs of Life?

The alien set made from Xenohide and Xenoid Alloy is the late-game best. Steel Combat is the reliable mid-game set.

Does armor have set bonuses?

Some sets do. Ghost Hide reflects two damage, and Energy Plate provides a recharging force field.

Should I wear a mining suit in combat?

No. Use it for mining and exploration; switch to a combat set for bosses.

Can I upgrade armor?

You craft new tiers through the workbench chain rather than upgrading a single piece indefinitely.
