About This Game
⚠️ Game servers may be susceptible to "migrating", aka restarting often due to being outdated. Please be aware of that at all times, especially during early releases. This will not usually be in effect though.
Buried deep within an undisclosed mountain range, there's a facility which is (quite literally) just as dumb as it can possibly get. And however owns this place? Yeah they seem a little paranoid for a place owned by a lava lamp company.
"A Core Game", or ACG, is supposed to be an accurate representation of your average "core game" on Roblox. Even though this has changed over the past few years, the game still takes inspiration from a few titles of the same genre.
