About Remnants
Post-Collapse Idle Survival — Free Browser Game
REMNANTS is a browser-based post-apocalyptic idle and incremental survival game. You start with nothing — a crumbling shelter, a handful of scrap, and one directive: rebuild. Collect resources, construct buildings, grow a colony, research new technologies, survive raids, run expeditions into the wasteland, and drag civilization back from ash. No download, no account, no cost.
The game draws on the incremental genre — think Cookie Clicker or Kittens Game — but layers in meaningful decisions: which buildings to prioritize, when to run an expedition versus when to hold back your population, and how to balance power consumption against production. Every run ends with an Echo Reset prestige that permanently strengthens your next playthrough, rewarding depth over time.
Core Systems
Resource Economy
Balance Scrap, Food, Water, Power, Population, Tech, Influence, and Archive Points across automated and manual production chains.
Base Building
Unlock and upgrade 30+ structures across four tiers: Base, Survival, Colony, and Beyond. Each building upgrades independently.
Research Tree
Spend Tech Points to unlock new buildings, automation, bonuses, and systems. Research gates progression and forces strategic choices.
Expeditions
Deploy squads on 9 missions across 3 tiers. Risk real population casualties on failure. Unlock Specialists, Blueprints, and Archive data.
Raid Defense
Raiders attack on a timer. Build walls, watchtowers, and armories. Repel waves to earn Caches and Influence — or lose resources on breach.
Scavenging
Send scouts to 7 wasteland zones. Flip hazard cards for resources. Card values scale with your production rate. Risk vs reward.
Echo Forge & Prestige
Complete a run to unlock Echo Fragments. Spend them on 20 permanent upgrades across 4 tiers that carry over to every future run.
World Archive
A 10-chapter MERIDIAN story arc unlocks one chapter per run. Discover what caused the Cascade and who the Commander really is.
100 Achievements
Track your progress across Raids, Expeditions, Scavenging, Prestige, and more. Includes hidden achievements with secret unlock conditions.
By the Numbers
30+ Buildings
Across 7 panels — Scavenging, Food, Water, Power, Population, Defense, and Diplomacy. Each upgrades independently.
8 Resources
Scrap, Food, Water, Power, Population, Tech, Influence, and Archive Points — each with its own production chain and consumption curve.
19 Research Nodes
From Efficient Smelting to Fusion Theory and City Planning. Prerequisites chain across the full tree. Last research requires 3 prior nodes.
100+ Achievements
Across 10 categories. Completions raise your Morale multiplier — making achievement hunting mechanically rewarding, not just cosmetic.
22 Forge Upgrades
Permanent cross-run bonuses in the Echo Forge across 4 tiers. Stack indefinitely across resets.
9 Expedition Missions
Across 3 risk tiers, with 6 named Specialist survivors to rescue — each carrying a unique permanent passive bonus.
500ms Tick Rate
The game loop runs every half-second. Speed multipliers (2×, 4×) genuinely scale production — not just cosmetic acceleration.
×1.15 Cost Scale
Building cost formula per additional unit. Deep runs with high building counts see genuinely exponential cost curves — not linear progression.
10-Chapter Story
The MERIDIAN arc unlocks one chapter per run. Completing the full story requires multiple prestige cycles.
Design Philosophy
A few deliberate decisions that shape how REMNANTS plays:
- No stamina, no energy gates. You play at your own pace. Nothing locks you out after N actions.
- No ads, no microtransactions, no paywalls. The full game is free. Every system is accessible from minute one.
- Decisions over clicking. Early game requires manual input. Mid-game is about building the right automation chain. Late game is optimization — not grinding.
- Offline progress is real. Resources accumulate while you're away. Returning after 8 hours should feel good, not punishing.
- Prestige rewards depth, not time. Echo Reset fragments scale with how well you played, not how long you waited. A fast, efficient run beats a slow slog.
- Story is optional but earns its place. MERIDIAN is there for players who want it. The lore explains the mechanics — the Cascade is a reason, not just flavour.
