LOWELL, MA, June 23, 2026 – Nitrous Butterfly is excited to announce the release of the "Upgrade Update" (Version 0.5) for its first-person cleaning simulation game, P.A.C.K. :: Post Apocalyptic Cleaning Kit. This major milestone introduces a new player progression system, significant quality-of-life improvements, and fresh content for players to explore.
In P.A.C.K., players step into the chassis of a cleaning robot, alone or with friends, tasked with restoring abandoned structures in the aftermath of a global catastrophe. With the introduction of the Upgrade Update, players can now enhance their robot’s attributes to optimize their cleaning efficiency. By converting resources acquired during missions into "Upgrade Scrap," players can unlock various performance upgrades via a newly overhauled in-game menu, which also provides detailed insights into level progression.
This update also invites players to explore the "Lost Chapter" Bookstore, a brand-new map packed with unique challenges and additional story elements.
Key Update Features:
- Player Upgrades: New progression system allowing players to improve robot attributes using Upgrade Scrap.
- New Map: Explore and restore the "Lost Chapter" Bookstore.
- Quality of Life Improvements: Addition of a player sprint mechanic, overhauled cleaning radar visuals for improved visibility, and a new "User Manual" to assist with gameplay.
- Enhanced Mechanics: Repair interactions now require a button hold, and flashlight intensity has been updated for consistency across all environments.
- UI Overhaul: Updated fonts and visuals throughout the game for better readability and clarity.
To fully experience the new progression systems and balance changes, it is recommended that players begin a fresh playthrough using the new "Reset All Progress" button found in the settings menu.
P.A.C.K. :: Post Apocalyptic Cleaning Kit is currently available in Early Access. For more information, visit the game’s website, join the community on Discord, or follow updates on Facebook and Patreon.
