Scavenging

Mechanics Guide - Remnants: Post-Collapse Idle Survival

Overview

Scavenging is the early-to-mid-game burst-reward system. Instead of waiting on passive production, you send survivors out to pick through the ruins for an immediate haul of resources. Every run is a small push-your-luck minigame: a ruined location offers a grid of face-down cards, and you flip them one at a time to claim loot - or trip a hazard.

The Scavenging panel unlocks at shelter level 2 once the Population system is active and you have at least 3 survivors. Launching a run requires at least 5 people in the settlement, since you are sending a crew out into the wasteland.

How a Run Works

• Press Scavenge to roll a random ruin location. Each location reveals a grid of 6 cards.
• Flip cards one at a time. Each card is either a resource reward or a ☢ HAZARD.
• Reward values scale with your current production rate, so a run is always proportionally useful - never trivial, never trivializing.
• When the grid is exhausted, the run ends and a cooldown begins before you can scavenge again.

Ruin Locations

The location is chosen at random each run and determines the bias of the loot table - what you are most likely to find. Every location carries some hazard weight.

Loot Card Types

• Resources - scrap, food, water, tech, and power cells, valued against your live production rate.
• Supply Cache - feeds the Expeditions blueprint economy. Cache and Archive cards only appear once Blueprints are unlocked; before that they are replaced with scrap.
• Memory Shards - the World Archive currency, most common at the University Library.
• 👥 Survivors - a small population boost (1-2 people), most likely at the Apartment Block.
• ☢ Hazard - the only bad card. It costs you the equivalent of 60-100 seconds of scrap production, so it always stings more than a single resource card rewards.

Cooldown & Watchtowers

After each run, scavenging goes on cooldown. The base cooldown is 8 minutes. Every Watchtower you build improves your scouting and shaves 45 seconds off the timer, down to a floor of 3 minutes at 5 towers.

Strategy

• Scavenge on every cooldown. Empty cooldown time is wasted value. Run it the moment it is ready, especially during active play.
• Build Watchtowers early. More frequent runs compound over a session, and the towers help your raid defense at the same time.
• Flip cautiously when ahead. Each flip is a fresh hazard chance. If a run has already paid for itself, there is no shame in being glad the grid is nearly done.
• Hit the University Library for the Archive. When you are reconstructing the World Archive, Memory Shards from the Library run accelerate transmissions.
• Hunt the Apartment Block for population. Survivor cards are a meaningful early bump toward your next building unlock and the population scrap dividend.
