Immunivax Injector
The Immunivax Injector is a 160-credit medical item that comes in four states: genuine, expired, unusable and counterfeit. You tell them apart with a Magnifying Glass and the Immunivax Assessment Guide by checking the serial number, label, colors, body and indicator. If you start with the Sentinel Collapse Disorder perk, you also need a genuine injector roughly once a week to stay alive.
| State | Value | Main tell |
|---|---|---|
| Genuine | 160 credits | everything matches the guide |
| Expired | 80 credits (−50%) | expired indicator |
| Counterfeit | 40 credits (−75%) | wrong serial, colors or label |
| Unusable | 8 credits (the label shows −90%) | empty indicator, cracked body or recalled batch |
When do Immunivax Injectors appear?
On day 25 the Immunivax Assessment Guide shows up on your counter, and from then on injectors start coming in with sellers. If you start with Sentinel Collapse Disorder, they are in play from day 1: you begin with one genuine injector, the guide, a Magnifying Glass and a note about the disorder.
How do I check if an Immunivax Injector is genuine?
Pick up the Magnifying Glass, inspect the injector and compare it with the Immunivax Assessment Guide. A genuine injector has all of the following:
- Serial number: seven digits. The first three digits are the batch, from 125 to 455, followed by four more digits.
- Batch not recalled: the recalled batches are 250, 251, 301, 355, 385, 386 and 421.
- Label: the company name reads exactly Carmicheal Pharmaceutical and the product name exactly Immunivax.
- Colors: the correct body colors.
- Body: no cracks.
- Indicator: fresh, neither expired nor empty.
If you find a problem, confront the seller. A correct accusation lowers the price. A wrong one costs reputation, as with other counterfeits (see the Counterfeits guide).
What does a counterfeit look like?
A counterfeit always has exactly one flaw, and each of these four is about equally likely:
- Bad serial number. Most often it is missing entirely. Otherwise it has six or eight digits, or starts with 100–124 or 456–999.
- Wrong colors.
- Misspelled product name, for example Immunovax, Imunivax, Immunivaxine, ImmuniVax 3000, or none at all.
- Wrong company name, for example Micheal Pharmaceutical, Carmicheal Inc., Carmicheal Pharmaceutical Ltd., or none at all.
What makes an injector unusable or expired?
An unusable injector is genuine but defective, with one of three problems: an empty indicator, a cracked body, or a serial number from a recalled batch. An expired injector looks genuine except for the expired indicator.
Customers can catch a bad injector you sell them, but they never notice a recalled batch. Batch 421 is on the recall list, but in version 0.46D the game never generates a serial with it, so in practice you will only see the other six recalled batches.
Where do I get Immunivax Injectors?
| Source | What you get |
|---|---|
| Upper Level Pharmacist | 50% chance of a random injector (stolen goods) |
| Scavenger | random injector, sometimes |
| Thief | genuine injector, sometimes (stolen goods) |
| Scalper | genuine injector |
| Underground Exchange | promotional exchanges: 2 Oxymore Injectors for 1 genuine Immunivax; 4 Vials of “Dream Dust” can pay out Immunivax from an average purity of 45%, more often the purer they are (from 99%, up to 3 injectors) |
| Secret Admirer perk | once per run, a genuine injector with a gift, if you have Sentinel Collapse Disorder and no usable one |
| Loot crates | can contain genuine or counterfeit ones |
A random injector from a seller is genuine about 42% of the time, expired 20%, unusable 20% and counterfeit 18%. Always check before you pay full price.
Why does Sentinel Collapse Disorder need Immunivax?
Sentinel Collapse Disorder is a negative starting perk worth 3 points. You can only use Immunivax Injectors if you have it. Each night without an injection counts up:
| Nights since the last injection | Effect |
|---|---|
| 6 | warning: you start to feel off |
| 7–9 | +1 damage per night |
| 10–13 | +2 damage per night |
| 14 or more | +3 damage per night |
Damage never heals during a run. At 20 points the run ends with the Sentinel Collapse ending. Without any injections, that happens on the 16th night. To take no damage at all, inject before your 7th night.
Which injector you use matters:
- Genuine: resets the count to 0.
- Expired: resets it to 3, so you get 3 fewer safe days.
- Counterfeit: resets it to a random 3–5.
- Unusable: does nothing, and the injector is used up.
Keep a genuine spare, and check every injector you buy with the Magnifying Glass.
FAQ
What is the Immunivax Assessment Guide? It is the reference sheet for checking injectors. It arrives on your counter on day 25. With Sentinel Collapse Disorder you have it from the start.
How much is an Immunivax Injector worth? 160 credits if genuine. An expired one is worth 80, a counterfeit 40 and an unusable one 8.
Which Immunivax batches are recalled? 250, 251, 301, 355, 385, 386 and 421. An injector from a recalled batch is unusable. Batch 421 never actually appears in version 0.46D.
Can I use Immunivax without Sentinel Collapse Disorder? No. Without that perk the injector cannot be used; you can only trade it.
How often do I need an injection with Sentinel Collapse? At least once every 6 days. Damage starts on the 7th night without one and is never healed.
