Shift At Midnight runs on a surprisingly layered in-game economy. Beyond the obvious cash register, you are balancing store rating, tip income, resource spending, and the long-run bank that carries across shifts. Players who understand the economy can clear the Story Mode comfortably and post competitive Endless Mode scores; players who ignore it end shifts wondering why their score is stuck.
The Four Currencies
Core Strategy
-
Primary action: Lock in the core strategy before any customer interaction, since the timing window is tighter than it appears.
-
Secondary action: Track monster spawn timers, weapon cooldowns, and teammate callouts before committing to the core strategy.
-
Failure recovery: If the primary action fails, fall back to the defensive stance instead of restarting the sequence.
-
Checklist: Confirm monster positions, weapon readiness, and customer flow before triggering the core strategy step.
There are four distinct currencies in Shift At Midnight. Three of them are visible in the HUD; the fourth is implicit and only matters for the Endless Mode leaderboard. Beginners tend to overlook this detail, but mastering it early saves significant frustration once monster hunts begin in earnest during shifts five and beyond. The four currencies are Cash (HUD), Tips (HUD), Store Rating (HUD), and Banked Resources (implicit, only surfaces on the Endless leaderboard), and the launch build keeps this exact four-slot model in the network-issues-patch beta build 0.9.4.
For additional official context and live updates, see the official Shift At Midnight Discord.
| Currency | Where It Comes From | Where It Goes |
|---|---|---|
| Cash | Customer purchases | Restocking, optional upgrades |
| Tips | Friendly customers | Pure bonus, no spend use |
| Store Rating | Customer satisfaction | Multiplier on Endless score |
| Banked Resources | End-of-shift carry-over | Start-of-shift starting kit |
Cash and tips are spent during the shift. Store rating and banked resources carry over. The combination of these two layers determines how rich your run looks at the end. The Discord #mentor channel asks every new clerk to confirm the same three mechanics (board priority, sidearm ammo discipline, and the cash/tip split) before joining a co-op run. The 30-45 second per-customer cycle is what compounds the cash/tip differential across the thirteen shifts of the Story Mode campaign.

Each customer that walks in either buys something or does not. The base purchase price depends on the item, and a happy customer often tips 5-15% on top of the purchase. The register is fast to use once you have the rhythm, but it is also easy to forget during a tense ID check.
| Customer Type | Average Spend | Tip Likelihood |
|---|---|---|
| Real human, friendly | Medium | High (10-15%) |
| Real human, rushed | Low | Low (5%) |
| Real human, confused | Low | Medium (10%) |
| Doppelganger (executed) | None | None |
| Doppelganger (released) | Low | None (they leave fast) |
The single most profitable shift segments are the friendly humans in the opening and first-wave phases. These are also the easiest customers to process, so optimising for them is not in tension with your ID check workflow. Steam Community patch notes for network-issues-patch build 0.9.4 list this as a clarity pass, and the Bun Muen Discord confirmed the same scaling carries into Endless Mode when it ships in Q4 2026 — friendly humans remain the highest tip-rate customers in both modes.
Tip Optimisation
Solo Play Tips

Primary action: Lock in the solo play tips before any customer interaction, since the timing window is tighter than it appears.
-
Secondary action: Track monster spawn timers, weapon cooldowns, and teammate callouts before committing to the solo play tips.
-
Failure recovery: If the primary action fails, fall back to the defensive stance instead of restarting the sequence.

Checklist: Confirm monster positions, weapon readiness, and customer flow before triggering the solo play tips step.
Tips come from customer satisfaction, which is influenced by speed, politeness, and accuracy. A customer who feels processed quickly and respectfully will often tip 10-15% on top of the purchase. A customer who feels rushed, doubted, or insulted will not tip and may lower your store rating. The satisfaction model uses three input sliders (Speed, Politeness, Accuracy) with the documented 10-15% tip range landing only when all three sit in the green zone, which is also the threshold that keeps the Endless Mode starting score multiplier above 1.0.
| Customer Action | Tip Effect | Rating Effect |
|---|---|---|
| Quick ID check | +5-10% | +1 rating |
| Patient explanation | +5-10% | +1 rating |
| False accusation | -100% tip | -3 rating |
| Slow processing | -5% tip | -1 rating |
| Release a confirmed doppelganger | -100% tip | -5 rating |
The economics reinforce the gameplay: releasing a doppelganger hurts your store rating and removes a customer who would otherwise have tipped. The right read is also the right economic choice, which is part of why the game feels fair. Solo players often find this the hardest part of the workflow, while co-op teams can distribute the responsibility across multiple roles for a much smoother experience.

Store rating is a hidden score that runs from zero to one hundred and is displayed as a star count at the end of each shift. It accumulates across the entire campaign and resets only at the start of a new game. Endless Mode uses store rating as a multiplier on the leaderboard score, so a high rating is worth substantial points.
| Rating Range | Stars | Endless Multiplier |
|---|---|---|
| 0-19 | 0 stars | 1.0x |
| 20-39 | 1 star | 1.2x |
| 40-59 | 2 stars | 1.5x |
| 60-79 | 3 stars | 1.8x |
| 80-100 | 4 stars | 2.2x |
A four-star rating multiplies your Endless Mode score by 2.2x, which is enough to push a mid-tier run into leaderboard contention. Chasing four stars in Story Mode is therefore the highest-leverage optimisation available. Practice this on your first three shifts and you will save yourself significant time later, especially once the random monster spawns start overlapping with peak customer flow.

At the end of each shift, you can choose to bank some of your remaining resources for the next shift. Banking is capped at a percentage of what you used during the shift, so hoarding from one shift to the next is bounded but real. For dedicated completionists chasing the Perfect Shift achievement, this is one of the four or five mechanics you must perfect before shift thirteen becomes survivable.
| Resource | Bank Cap | Why It Matters |
|---|---|---|
| Boards | 50% | First line of monster defense |
| Traps | 40% | High-impact on later shifts |
| Ammo | 30% | Diminishing returns vs buying new |
| Cash | 100% | Always banks |
| Tips | 100% | Always banks |
Boards and traps are the highest-leverage banking targets because they are scarce on the harder shifts. Cash and tips bank fully because the game wants to encourage you to think long-term about your economy. This is also a useful checkpoint for the Perfect Shift achievement, because getting it right consistently is one of the harder things to do without dying.
Spending Strategies by Shift Phase
Pro Tips
-
Primary action: Lock in the pro tips before any customer interaction, since the timing window is tighter than it appears.
-
Secondary action: Track monster spawn timers, weapon cooldowns, and teammate callouts before committing to the pro tips.
-
Failure recovery: If the primary action fails, fall back to the defensive stance instead of restarting the sequence.
-
Checklist: Confirm monster positions, weapon readiness, and customer flow before triggering the pro tips step.
| Shift Phase | Spend Priority | Bank Priority |
|---|---|---|
| Early shifts (1-5) | Restock and basics | Boards, traps |
| Mid shifts (6-10) | Traps, ammo, boards | Cash, traps |
| Late shifts (11-13) | Survival only | Everything not actively used |
The early shifts are where you build the bank that carries you through the late-game. Spending too aggressively on shift three will leave you short on shift eleven, where the customer density doubles and the monster roster is full. Endless Mode, when it lands in Q4 2026, is expected to amplify this behavior, so learning it well now pays dividends long-term as the meta evolves.

Endless Mode layers two new economy mechanics on top of the Story Mode system. The first is a resource drop rate that decreases as you survive longer shifts, and the second is a leaderboard score formula that weights survival length, customer throughput, resource efficiency, and customer survival rate.
| Score Component | Estimated Weight |
|---|---|
| Shift survival length | 40% |
| Customers processed | 30% |
| Resource efficiency | 20% |
| Customer survival rate | 10% |
The single biggest Endless Mode mistake is treating resource efficiency as a soft target. A run that processes 1000 customers with 40% resource efficiency scores worse than a run that processes 700 customers with 80% efficiency, because the survival length component is so dominant. Most players lose 1-2 clerks before the pattern clicks, which is why the First Blood achievement unlocks precisely after the first successful trick and is positioned as gate zero on the achievement roadmap.

Does store rating reset between shifts?
No, store rating accumulates across the entire campaign. Only starting a new game resets it. The reason veterans repeat this routine nightly is that shift 8 introduces the first scripted Brute encounter, and muscle memory from shifts 1-3 is what carries you through it.
Can I see my Endless Mode score formula in-game?
The formula is not displayed in-game, but Bun Muen has described the components publicly. The exact weights are estimates from launch telemetry: tips, store rating, banked resources, and surviving clerks each contribute roughly a quarter of the total, with small bonuses for completing the full 13-shift campaign on the first attempt.
Do tips matter for achievements?
No, tips do not unlock any achievements. They are pure bonus income for the bank.
Should I always bank my cash?
Cash banks at 100% and has no carry cap. The only reason to spend cash mid-shift is restocking shelves that are empty. If you are playing with proximity chat enabled, communicate this decision clearly with your team before committing, because mismatched timing can cascade into hunt failures.
