You ever stumble on a game so weirdly specific it makes you pause mid-scroll? BioGun is that game. It’s a vaccine-themed shooter (yep, you read that right) where you blast viruses from inside a dog’s body. Now, that alone might not raise eyebrows—until you realize everyone’s suddenly Googling “BioGun trial codes” like it’s the next Steam sale hack.

Why? Well, early access is live, and these clinical trial codes? They’re your ticket to free in-game rewards, early perks, and a head start in this quirky little indie title. You’re not just playing—you’re participating in a trial. Wild.

Let’s break down what these codes actually do—and why U.S. players can’t stop searching for them.

Active BioGun Codes for November 2025 (U.S. Region Only)

Alright, if you’re anything like me, you’re checking this list right before booting up BioGun—just to make sure you’re not missing a juicy booster or one of those weird-but-fun secret unlocks. BioGun’s November patch dropped with some really solid limited-time drops (Thanksgiving-themed ammo skin? Yes please), and yep—U.S.-specific trial codes are part of the mix again.

Here’s what’s still active this month (I’ve tested these myself—if one doesn’t work, it probably just expired yesterday. It happens.):

How to Redeem BioGun Codes on iOS & Android (U.S. Players Guide)

You’d think redeeming a code would be the same on every phone, right? Nope. What I’ve found with BioGun is that the process is just different enough between iPhone and Android to trip you up if you’re not paying attention. I’ve done this a few times now (and yeah, once totally thought a code was broken when it was just me being on the wrong screen).

Here’s what works—step by step—for U.S. mobile players:

iPhone (iOS – App Store build):

• Launch the BioGun app and wait until you’re at the home screen (sometimes it hangs—just give it a sec).
• Tap the gear icon in the top-right (that’s your settings menu).
• Scroll down and hit the “Redeem Code” option (it’s buried, but it’s there).
• Paste your code (don’t type—autocorrect will mess it up, trust me).
• Tap Confirm. You’ll get a green confirmation message if it works.

Android (Google Play version):

• Open BioGun and head straight into the main menu.
• Tap the in-game store icon—yep, the little syringe thing.
• At the bottom, there’s a “Promo Code” button (sometimes it glitches—you might have to restart if it’s not clickable).
• Enter your code and tap Submit.
• If you get a “Code Invalid” error, check that you’re using the correct region (US-only codes won’t work elsewhere).

Tips to Never Miss a New BioGun Code Drop

If you’ve ever missed a limited-time BioGun drop by like… an hour, you’re not alone. I’ve had at least two “what do you mean that code expired?” moments this year. So here’s how I stay ahead of the chaos—without doom-scrolling Discord every five minutes.

These are the tools and habits I actually use to catch code alerts the moment they go live:

• Turn on in-game push notifications.
  This sounds basic, but I turned them off once to save battery and boom—missed a Halloween skin drop. Most U.S. region drops come through BioGun’s internal alerts first.
• Follow @BioGunOfficial and add them to a Twitter/X List.
  I’ve got a custom “Code Watch” list (just U.S. game devs and promo bots). You can enable mobile notifications for that specific list, which is way cleaner than drowning in your main feed.
• Use Reddit’s /r/BioGunGame + Reddit alert bots.
  Set up a keyword tracker (I use Notifier for Reddit) for phrases like “new code” or “event drop.” I usually get pinged within five minutes of a post going live.
• Enable browser notifications for Steam News and dev blogs.
  Especially useful if you’re playing the mobile version but the devs drop announcements through Steam patch notes. Weird, but it’s happened.

What I’ve found is, it’s not about checking constantly—it’s about setting up instant alerts and letting the system work for you. Honestly, anything that gives me a 10-minute head start on limited drops? Totally worth the few setup steps.
