Surviving overtime
What exactly happens when the phase clock runs out — and how to use it without dying trying.
What overtime is
Each phase lasts 10 minutes. If you're still on the map when it runs out, you enter overtime: difficulty, which until then climbed a gentle +3% per minute, starts climbing +60% per minute. And if you've already killed the boss and still stick around, the pace rises to +150% per minute. The game calls it "advance or die" for a reason.
Everything that speeds up
It's not just enemy damage and health. In overtime, spawn rate also grows (+50%/min before the boss, +90% after, up to ×6) along with enemy movement speed (+7%/min before, +18% after, up to ×1.9). After the boss dies, finisher waves also appear: every 60 seconds, 4 + 1 per minute (up to 12) charging at you at ×1.8 speed.
How to get out
The only way out of overtime is through the portal, and only the phase boss opens the portal. When the map turns impossible, remember the order: kill the boss, cross over, and start the next phase at floor difficulty (the overtime ramp is wiped when you cross).
