About Undefined's Upgrade Tree
WELCOME TO UNDEFINED'S UPGRADE TREE!! :OO In this ((SINGLE PLAYER)) world, there is no limits on how FAR you can go! Will you be the NEXT person to break the game's limits..? ⚠ - This game is in BETA please be patient. It gets updated everyday, for bug fixes. ✨ There is currently 11 stats and 10 layers to explore.. I will slowly add more mechanics to the game every time ;) 🫵 Expect more content everytime! :L ❓ - RULES -> Expoits (such as lag switching, macros, etc) are not allowed. What you think is not allowed is not, use common sense. ↑ You can get banned from the game too, there is secret anticheat. -> You might encounter bugs. Please report them in the group or use the bug report UI in-game!! :D -> There is a tutorial in the game, if you dont know how to play, join it. 🌐 - CREDITS This game is inspired by many other upgrade trees. There is no 'specific' upgrade tree that was my main inspiration. It's a passion project! :) { Another awesome ROBLOX experience.. hopefully! c: }
