The Room Priority Tier List
| Tier | Room | Effect (demo-verified) | Why |
|---|---|---|---|
| S | East Wing Resolve (stamina track) | +20 max stamina at level 4 | Universal value — faster extracts, better flanks; helps every role |
| S | Inventory tier rooms | Tier 3 unlocks sword, hammer, gun | The single largest combat power spike; gate deep-layer pushes behind it |
| A | Health rooms | +20 HP at demo max | Fewer accidental Spark transitions; anchors feel it most |
| A | Damage rooms | +20% damage at demo max | Scales with melee skill; pair with inventory tiers |
| B | Secondary wings | Partial stat bumps | Once S/A rooms cap; value grows if launch raises ceilings |
| B | Workshop utility rooms | Artifact-rolling QoL | After combat stats stabilize |
| C | Cosmetic tiers | Color rows for construct customization | "They do not save runs" — cap functional rooms first |
| C | Heavy decor rooms | Aesthetics | Risky: elevator Rot incidents can destroy layouts |
East Wing Resolve, Explained
The East Wing Resolve is the Outpost's stamina track and the most universally recommended first upgrade. Demo level four granted +20 max stamina — and stamina is extraction insurance: it extends sprints during elevator pulls, widens kiting windows, and speeds up fuse hunts and shop sweeps. When your crew's failures are timing failures rather than kill-speed failures, stamina is the fix.
Gold Costs (Planning Estimates)
| Upgrade | Approx. cost in run-equivalents |
|---|---|
| Early stamina levels | 1–2 successful shallow runs |
| Inventory tier gates | 3–4 coordinated mid-band runs |
| Cosmetic tiers | Defer until S-tier functional rooms are capped |
Role-Based Priorities
| Co-op role | First rooms |
|---|---|
| Anchor | Damage, health |
| Carrier | Inventory, stamina |
| Scout | Stamina |
| Flex | Inventory |
Solo adjustment: stamina and health move up a tier; damage drops one — survivability over kill speed. Outpost progression applies to the shared base in co-op, so agree on spending before anyone clicks.
Four-Week Sprint Plan (New Crew)
- Week 1: East Wing Resolve stamina to its first major perk
- Week 2: Inventory tier two on the designated Carrier
- Week 3: Health or damage wing, based on wipe analysis
- Week 4: Deep-layer attempts only after tier-three inventory on at least one player
Frequently Asked Questions
What should I upgrade first in the GRAIN ROT Outpost?
East Wing Resolve stamina (+20 max stamina at level 4 in the demo), then inventory tiers — tier three unlocks the sword, hammer and gun, the biggest power spike in the game.
Are Outpost upgrades shared in co-op?
Yes — room progression applies to the shared base, so crews should agree on spending order (functional rooms before cosmetics) before anyone buys.
