Kingdom Rush 6 FAQ

Short answers to what players run into first. Launch fixes come from Ironhide’s own known-issues post.

Getting it running

Steam says the executable is missing (0 KB) or asks for a CD key

Ironhide fixed this on its side on launch day. 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

Delete settings.lua and global.lua from the game's settings folder, start the game, and hold left Alt (Option on Mac) when the splash sound plays until the resolution window appears. 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.

Controls and settings

Can I change the keybinds?

Yes, inside a stage: open Settings and go to tab 4. Keybinds for the other screens were promised for a later update.

Does it support a controller?

Partly. Steam lists partial controller support, and the mouse alone is enough to play.

Are saves in the cloud?

On Steam, yes: the game supports Steam Cloud.

What languages is it in?

10 on Steam, with full voice acting in English: English, French, German, Japanese, Korean, Brazilian Portuguese, Russian, Simplified Chinese, Latin American Spanish and Traditional Chinese.

How the systems work

Can I change tower upgrades?

Yes. Tower upgrades are global, one tree per tower line, and you can change them between stages.

Do I keep XP and gems if I lose?

Gems, yes: they drop from enemies and stay yours win or lose. Spell XP is kept even when you lose, restart or quit a stage. XP planner

How many heroes can I bring?

2 heroes, 5 towers and 3 spells per stage. Hero Party allows four heroes and no spells; Classic Rush allows one. Loadout planner

How many stages are there?

18 in the campaign, each with five extra modes. Two mini-campaigns of three stages each are planned before the end of the year. All 18 stages
