Expeditions

Mechanics Guide — Remnants: Post-Collapse Idle Survival

Overview

Expeditions are squad-based missions you send into the wasteland from the Expeditions panel. They run on a timer and return with rewards — or casualties, if things go wrong. Expeditions are the primary source of Influence, Archive Points, Blueprints, and rare Specialists.

Unlike most systems in REMNANTS, expeditions require active decisions: which mission to send which squad to, how many population to commit, and whether to boost with Influence. Getting expeditions right significantly accelerates mid- and late-game progression.

Unlocking Expeditions

The Expeditions panel unlocks automatically at Shelter Level 3 — no research required. Push for Shelter 3 once your Food/Water production is stable; the panel appears in your sidebar and missions become available immediately.

Mission Tiers

There are 9 missions across 3 tiers. Higher tiers offer better rewards but carry real casualty risk.

Risk & Casualties

Each mission has a risk threshold — a minimum effective squad size. Sending fewer population than the threshold increases the chance of failure and casualties. Failure on high-tier missions kills members of your deployed squad.

• Casualties are permanent within the run — lost population reduces production until it recovers naturally.
• The mission card shows current risk level before you deploy.
• Upgrading your Research (Expedition Protocols and related) reduces the effective risk of missions and increases squad survivability.
• Certain Forge upgrades and Specialists also reduce expedition risk passively.

Rewards

Expedition rewards scale with mission tier and run depth. The primary reward categories:

• Influence — used for Faction Treaties and the Expedition Boost button.
• Archive Points — the currency for Blueprint and Archive Research trees.
• Blueprints — special items that unlock Tier 2 buildings and unique bonuses via a separate research track.
• Caches — condensed resource packages (Scrap, Food, Water mix).
• Specialist Rescue — certain missions offer a chance to rescue a named Specialist survivor.

Blueprint and Archive research costs were deliberately raised in v1.1.0 — you'll need multiple runs and consistent expedition cadence to unlock everything in these trees. This is intentional: expeditions should be relevant across your entire run, not just an early bonus.

Specialists

Specialists are 6 named survivors scattered across the wasteland. Each grants a permanent passive bonus while present in your colony. They persist through Echo Resets.

Blueprints & Archive Research

Expeditions fund two separate research trees not visible until you have enough Archive Points:

• Blueprint Research — Blueprints are dropped on specific missions. Each Blueprint unlocks a unique building or system. Key examples: Grid Schematics, Diplomatic Cipher, advanced production structures.
• Archive Research — Spent Archive Points unlock multipliers, production bonuses, and quality-of-life improvements. Costs scale steeply — plan across multiple runs.

Both trees have costs that were raised 2–3× in v1.1.0. You will not unlock everything in a single run. Treat these as cross-run investments, not single-session goals.

Faction Treaties

Five wasteland factions can be allied via the Diplomacy panel (unlocked through research). Spending Influence Bonds on a faction grants a permanent passive bonus for that alliance. Factions include resource bonuses, population growth boosts, and combat multipliers.

• Influence Bonds are generated by expeditions and certain buildings.
• Bond progress persists through Echo Resets.
• The Diplomat Specialist improves faction treaty rates.
• Faction bonuses stack — allying with multiple factions compounds over time.

Influence Boost (⚡)

Each active mission card has a boost button (⚡). Spending Influence on it accelerates the mission — either shortening the timer or improving success odds depending on the mission type. Useful when:

• You need an Archive Point injection urgently before a research deadline.
• A Specialist rescue mission is running low-odds and you want to push it over the threshold.
• You have excess Influence and no immediate Faction Bond to spend it on.

Strategy Tips

• Always have missions running. Empty expedition slots are dead time. The moment a mission completes, queue the next one.
• Echo Forge: Extended Network adds +1 expedition slot. A huge throughput increase — prioritise it if you run expeditions hard.
• Don't always max squad size. Sending 10% more population than the risk threshold is enough. Save population capacity for production and raid defence.
• Cycle Tier 1 missions while grinding Archive. While your main squad runs a long Tier 3, fill shorter slots with fast Tier 1s for steady resource flow.
• Specialist missions appear rarely. When one appears, boost it — Specialists have outsized permanent value.
• Blueprint missions are time-limited in availability. Don't let them expire. Blueprints unlock buildings with no other source.
