Kingdom Rush 6 FAQ
Short answers to what players run into first.
Getting it running
Steam says the executable is missing (0 KB) or asks for a CD key
It has been fixed on Ironhide's side. Restart the Steam client and it goes away.
The game runs slowly
Open Options from the main menu (top left), go to page 5, and set FPS to 30 and/or turn off VSYNC. A display set to 30 Hz also causes it.
The resolution is wrong
Hold left Alt (Option on Mac) as the game starts: when the splash screen finishes, a launcher window opens where you set the resolution. If it does not appear, delete settings.lua and global.lua from the game's folder and try again. Folder paths for Windows and Mac
The hero's drag line freezes
A known launch bug, most often at path corners. Click a few times to clear the line.
The game crashes to the desktop
The engine update is in the main Steam version, 1.00.072. If crashes began after it, test the prev_version branch (1.00.052). Back up your saves first. If the crash persists, email support@ironhidegames.com with your system, what you were doing and the crash file if the game wrote one. Crash fixes step by step

How do I quit to the desktop?
