The Upgrades Shop in Residence Massacre is a daytime NPC booth that spawns across the road from the house in Endless mode. Operated by a Robloxian wearing a purple shirt and purple party shades, this booth allows players to spend earned cash on permanent utility upgrades for the generator, fusebox, and lightning rod, as well as structural repairs for doors and windows broken by The Mutant.
Utilizing the shop is necessary for enduring extended runs and unlocking achievements like the True Survivor and Loyal Customer badges.
Shop Location and Schedule
The Upgrades Shop booth appears during daytime hours on the opposite side of the main road. The booth is colored grey with two oversized wrenches mounted on top, neon purple "repairs & upgrades" signage, and an on-site radio playing an instrumental version of "arizona green tea rain forest" by CO$MO.
The shopkeeper alters his appearance during specific seasonal modifiers:
- Graves modifier: Wears a Witch Hat.
- Blizzard modifier: Wears Holiday Lights.
Because daytime ends promptly at 12:00 AM (midnight) when the next night begins—and because delivery trucks arrive at 6:00 AM and leave at 4:00 PM—players must manage daytime tasks carefully. If an Eclipse modifier triggers at 6:00 AM, the daytime sequence is replaced entirely by an extended combat phase, and no shop booths will spawn that day.
Upgrades List, Costs, and Effects
The shopkeeper sells specific station improvements alongside repair services. Upgrades persist across subsequent nights within that Endless session.
| Object / Station | In-Game Effect | Level Count | Upgrade Costs |
|---|---|---|---|
| Generator | Increases fuel capacity by +25 per tier (up to a 200-capacity cap). | 4 tiers | $15 baseline scaling ($15 × level number) |
| Fusebox | Increases the duration lights remain on before the box blows out and requires manual repair. | 5 tiers | $10, $20, $35, $50, $70 |
| Lightning Rod | Places a rod on the house roof to prevent lightning strikes from blowing the fuses during Thunderstorm nights. | 1 tier | Available for purchase at the booth |
| Window Repair | Fully replaces broken window frames destroyed by The Mutant. | Repeatable | Cash fee per window |
| Door Repair | Replaces doors broken during chases. | Repeatable | Cash fee per door |
Visual changes reflect your investment on the property:
- Purchasing the Lightning Rod visibly places it atop the roof.
- Upgrading the Fusebox changes its model incrementally across its 5 stages: Level 1 adds two bottom pipes; Level 2 darkens its grey frame; Level 3 mounts external side lights; Level 4 shifts to an even darker finish; and Level 5 installs red pipes on a dedicated floor pedestal.
The 40% Discount Quest
On the right side of the booth, a donation box lists items the shopkeeper needs. Fulfilling the request grants everyone on the server a 40% discount on all upgrades for that entire in-game day. The discount expires when the day concludes.
The NPC randomly requests one of two item recipes:
- Recipe A: 4 Hammers or Weak Hammers
- Recipe B: 2 Hammers (or Weak Hammers) and 1 Wrench
When to Donate (and When to Skip)
Hammers are critical survival assets used to barricade windows against The Mutant. A standard Hammer holds 3 charges, while a Weak Hammer has only 1 charge.
Donating fresh 3-charge hammers can leave you defenseless if your window defenses are breached during a Bloodmoon or Fog modifier. To maximize value without crippling your defenses:
- Loot the delivery truck crates at 6:00 AM for Weak Hammers, spare tools, and wrenches.
- Use 2 charges of a standard 3-charge Hammer on broken boards, then donate the remaining 1-charge Hammer to fulfill the shopkeeper's request.
- If you lack excess hammers or tools, skip the discount and pay full price rather than sacrificing your primary window fortification tool.
Best Upgrade Order and Strategy
Endless income is earned actively throughout the game: barricading windows ($2), placing cameras ($5 once), refueling the generator ($0–$4 depending on amount), fixing blown fuseboxes at night ($5), scaring off The Mutant ($5), and surviving the night ($15). With finite cash early on, prioritize purchases in this order:
- Generator (Tier 1 to Tier 4): Expanding fuel capacity to the maximum of 200 gives you significant breathing room. At max capacity, refuels last nearly entire nights, allowing you to focus on tracking The Mutant through auditory cues and Glowing Red Eyes rather than running outside to the shed.
- Lightning Rod: Purchase before or during heavy weather events. Thunderstorms randomly send lightning strikes into the house wiring. Without a rod, lights blow immediately, removing your ability to flash and repel The Mutant unless you risk a manual fusebox repair in the dark.
- Fusebox (Levels 1–5): Upgrading the fusebox increases tolerance against extended light usage, but it is secondary to generator security.
- Repairs (Situational): Only purchase door repairs if you rely on interior door-closing loops to kite The Mutant during chases. Window repairs are generally unnecessary if you have hammers and spare wood planks to board open frames.
Related Badges
Interacting with the Upgrades Shop contributes directly toward two official game badges:
- Loyal Customer: Awarded when a player maxes out every station upgrade (Generator, Fusebox, and Lightning Rod) in the Upgrades Shop. Structural door and window repairs do not count toward this achievement.
- Greatest Helper: Awarded by satisfying all daytime character requests in one run: donating the required items to the Upgrades Shop box, delivering gas cans to the Truck Worker, purchasing every drink at the Lemonade Stand, and returning two lemons to the lemonade vendor.
Frequently Asked Questions
Do upgrades carry over if I die in Endless mode?
No. All purchases made at the Upgrades Shop are tied exclusively to the active Endless run. Once all players die and the session concludes, your upgrades reset for the next run.
Why did the Upgrades Shop not appear in the morning?
Booths only appear during normal daytime sequences. If an Eclipse modifier activates at 6:00 AM, daytime is skipped, no NPCs will arrive, and The Mutant continues attacking until noon. Additionally, booth spawns across the road rotate among available NPCs (such as the Upgrades Shop and the Lemonade Stand).
Does repairing windows count toward the Loyal Customer badge?
No. Official badge criteria specify that only permanent equipment upgrades (Generator, Fusebox, and Lightning Rod) count toward Loyal Customer. Window and door repairs are consumable maintenance actions.
