Auto upgrading in Tower Defense Simulator
In Tower Defense Simulator, falling behind on upgrades is how runs are lost — the waves scale fast, and a tower that's a tier behind lets enemies through. Managing every upgrade by hand under pressure is tough. This script handles it: it upgrades your towers in the best order the instant you can afford each one, prioritising what holds the next wave.
It keeps your defence scaling without you watching the cash. Pair it with the auto play script for full automation and auto win to clear the toughest modes.
