Hello everyone!

This is one of the biggest updates to KeyBreach so far, introducing new operators, a brand-new Black Market system, B-SIDE features, achievements, and much more.

New B-SIDE Operators

Two new B-SIDE operators have been added:

  • THE BARON

  • THE LEAK

Unlock them by completing Difficulty 5 with:

  • Merchant → THE BARON

  • Exploit → THE LEAK


Black Market

A brand-new Black Market can now appear during SHOP sessions.

How it works:

  • First, you must completely clear the shop's inventory.

  • Once the inventory is empty, the Black Market has a 2% chance to appear.

  • In B-SIDE, this chance increases to 5%.

The Black Market offers rare and powerful deals you won't find anywhere else (have huge drawback as well for free!).


New Reroll Mechanics

You now have more control over your runs.

  • PROTOCOL SECTION floors can now be rerolled, allowing you to change your available GLITCH choices.

  • A new BIOS Upgrade lets you reroll one boss during your run.


New Neutral Items

Skipping Stone

Advance 2 floors immediately.

  • Can only be used on odd-numbered floors (3, 5, 7, 9, etc.).

  • Boss floors cannot be skipped.

VIP Card

Guarantees that the next eligible shop will open the Black Market.


New Achievements

Four new achievements have been added:

  • Speedrunner – Clear an Adventure Sector in under 10 seconds. (Client Only)

  • Black Market – Discover the Black Market. (Client Only)

  • MASTER BARON (Steam and Client)

  • MASTER LEAK (Steam and Client)


B-SIDE Features

B-SIDE has received several exclusive improvements:

  • 2× rewards for letter completions.

  • 50% fewer words required to complete each stage, making runs significantly faster.

  • A dedicated B-SIDE leaderboard.

  • The new Corrupted Shop inventory system.


Localization

  • Fixed operator names across all supported languages so they now use consistent naming.


Changes

  • 2 new music related to Black Market

  • Shop Items now have seperate lines for CONS and PROS

  • Sidebar menu where you see PERFORMANCE METRICS now have an accordion menu


Visual Update

I've also reworked KeyBreach's capsule art with a fresh new look!

As always, thank you for playing and for all the feedback. More content is already in development for B-SIDE, I still have to do 16 more operators...

Don't forget to leave a review to support the development.
