Progression

Waves, plot size and how far the game goes

Placement limit is the real progression bar, and the wave count runs much higher than most guides suggest.

Updated

Placement limit is the ceiling that matters

You start able to place 40 objects. That number climbs through the Place More skill line, and higher values were seen repeatedly across recordings. Every other upgrade is bounded by it — a stronger object you have no room for is worth nothing.

How far the game actually goes

Waves past 600 were reached in recorded footage, with coin totals near 921 million and base damage around 2.4 million per second. Guides that treat wave 30 as the endgame are describing the first hour.

Milestones are signposted in the HUD

The wave counter prints the next milestone underneath it — '??? at wave 40' and '??? at wave 50' were both captured. The game tells you when something changes; it just does not tell you what.

Build controls

Build mode has three tabs — Blocks, Weapons and Relics. Click places, R rotates, and the tilde key cancels. There is a clear-plot button, which matters more than it sounds: relayouts are frequent because placement limit rises in steps.

About bosses

Bosses are widely described as the centre of the endgame. Across roughly two hours of recordings from ten different players, no boss fight and no relic drop was captured — players spend their time at the crafting machine instead.

That said, the shop sells a gamepass called 2x Boss Drops, which only makes sense if bosses drop something, and relics are the material every crafting recipe wants. So the link is almost certainly real; we just have not been able to film it.

FAQ

Waves, plot size and how far the game goes FAQ

What is the highest wave anyone has reached?

The highest confirmed from footage is past wave 600. Higher runs almost certainly exist.

Are bosses important?

Less than most write-ups imply, based on what players actually spend their time doing on camera. Relics matter because recipes consume them, but boss fights themselves did not appear in any recording we reviewed.
