Custom Game Mode Beta is Here!
The Custom Game Mode Beta has finally hatched!
After months of clucking about it, the day has come.
We’ve opened beta test channels so you can finally crack open the upcoming Custom Game Mode before it rolls out to everyone.
This mode lets you bend the rules of New Yolk City until they squeak. Want total chaos? Go for it. Want a peaceful shop with zero cops?
Your coop, your rules.
How to join the Beta
Right-click the game in your Library Select Properties Open Game Versions and Beta Choose the branch custom-game-mode Update Prison Boss Prohibition
YOU WILL BE NOT ABLE TO PLAY CO-OP WITH PEOPLE WHO DIDN'T JOIN THE BETA
What you can mess with in Custom Game Mode
You’ll be able to cook up your own runs with options like: • Select up to 6 factions • Select up to 5 suppliers • Limitless cash register (no need to hide your cash in chests anymore) • Choose your starting money and reputation • Unlock everything immediately • Turn cops off entirely • Enable Daily Search (pull the clock early and a turbo cop will come to search your shop for any non-hidden illegal items) • Endless mode • No time limit for phases • The ability to spawn items (THAT'S CHEATING!)
Basically: total control over your smuggling empire.
We need your eggs-pert feedback
While you’re testing, please report bugs and feedback on Discord using the tag: Custom Game This helps us separate the good eggs from the cracked ones before the full release.
Thanks for helping us test this new mode and for patiently waiting while we incubated it.
Now go break the rules of New Yolk City. We promise not to tell the mayor.
Don't forget to check out our Socials and have a chat with other Eggs!
