To prevent running out of gold in Coop TD: Together, prioritize an economy-first strategy during waves 1 through 15 using Bounty, Ore, and Mimic towers. Securing your resource generation early gives you the capital needed to support high-cost defensive upgrades in the late game.

Early-Game Setup: Bounty and Ore Towers

Establishing passive income early guarantees steady gold flow regardless of wave clearance speed. Avoid spending all your starting gold on damage units; instead, deploy economic units as soon as the initial wave permits.

TowerCore FunctionBest Early Action
Bounty TowerGenerates passive gold continuously over time.Place 1–2 units immediately after wave 1 to start compounding returns.
Ore TowerProvides consistent resource income per wave cycle.Keep at a high upgrade level before purchasing additional attack towers.

If your gold income stagnates in the middle of a match, upgrade your existing Ore towers instead of placing new offensive units. The increased yield pays off quickly, keeping your cash flow positive.

Mid-Game Scaling with Mimic Towers

Board space becomes constrained as enemy waves grow stronger. The Mimic tower acts as a resource multiplier, simulating your highest-level economy towers without taking up the footprint of an extra full unit.

  • Target High-Level Units: Pair or position your Mimic tower next to your highest-level Bounty or Ore tower to duplicate its output.
  • Save Board Footprint: Using Mimics to scale gold generation leaves free tiles for dedicated damage-dealing towers needed later in the run.
  • Maintain Adjacency: Ensure Mimic towers are positioned in range of your primary Ore units to maximize total per-wave resources.

Balancing Defense and Economy

Over-investing in economy can leave your defense open to early defeat, while over-investing in attack towers causes late-game gold droughts. Maintain a positive net gold balance after every wave upgrade to verify your setup is on track.

If your gold reserve stays near zero after upgrading, pause offensive spending and deploy an additional Bounty or Ore tower. Once you pass wave 15 with a self-sustaining gold engine, transition your spending toward maxing out late-game damage dealers and replacing weaker towers on the fly.
