Confirmed controls
| Input | Action | Source |
|---|---|---|
| Mouse | Move the cursor, place and select turrets, aim, click skill-tree nodes | Gameplay trailer |
| Mouse click | Confirm a placement or a skill-tree purchase | Gameplay trailer |
| Z (QWERTY) | Remove a barricade; move a wall | Steam discussions, demo tooltips |
| Y (QWERTZ) | The same action on a QWERTZ keyboard | Steam discussions |
That is the complete set we can confirm from public sources. The game does not publish a key list, and the demo’s page has no controls section.
The barricade key, explained
The two most common questions on the Steam hub are “How to remove barricade?” and “Moving the walls”. The answers, from players:
“Press Z. I hope I didn’t write too late.” — barricade removal
“For non English layout keyboards: press Y” — same thread
“press y (on qwertz) or z (on qwerty)” — moving walls
So the game maps one key to both removing and moving a barricade/wall, and the letter changes with the keyboard layout. On an AZERTY keyboard, neither Z nor Y is in the same physical place as on QWERTY; if the game reads the letter, try both. If it reads the physical key, the QWERTY position is the one to press. We cannot confirm which, because the developer has not documented it.
What the interface shows
The trailer’s level-select and skill-tree screens show:
< LEVEL SELECTandSKILL TREEtabs at the top left.- Three currencies at the top: BASIC (white circle), CLEAR (blue triangle) and PERFECT (gold star).
×2andBUY A RANKcontrols at the bottom left of the skill tree.- A hover tooltip on each node with the name, effect and cost (for example, the Laser tooltip).
The skill tree is a large node map; in the trailer the view pans across it with the mouse. We have not confirmed whether there is a zoom control or keyboard navigation.
No controller, no rebinding (as far as we know)
- The store page’s category list is Single-player, Steam Achievements, Steam Cloud, Family Sharing — no “Full controller support” or “Partial controller support” tag.
- There is no key-binding section on the store page and no discussion thread about rebinding.
- The demo inherits the same categories, so do not expect controller support there either.
If you are buying for a Steam Deck, that is a real risk: the game wants a mouse for aiming and for the skill tree, and the Deck’s compatibility is rated unknown.
Controls you may be missing
- Skill-tree purchases are permanent-looking. The trailer shows costs deducted when a node is bought; we have not seen a respec button. Do not spend Perfect points on a turret you have not tested.
- The ×2 control is visible in the skill tree’s bottom-left corner. We have not confirmed whether it speeds up the game or the tree; treat it as a UI control to test in the demo.
- Tooltips are the manual. The game explains barricades, walls and node costs in hover tooltips, not in a separate tutorial. Hover everything once.
