To reach and clear Wave 80 in Normal mode in Coop TD: Together, build early economy towers, concentrate fully upgraded DPS towers in high-traffic central areas, and place crowd-control units near enemy spawn points. Transition out of weak early-game towers after Wave 50 to maximize damage output and gold efficiency.
Tower Positioning and Board Layout
Maximizing target coverage requires clear separation between control units and main damage dealers:
- Frontline Utility: Place slowing and debuff towers near enemy spawn points. Focus upgrade gold on maximizing slow or stun duration rather than raw damage to stagger incoming waves early.
- Central DPS Hubs: Build primary damage dealers in high-traffic middle paths to ensure maximum coverage time while enemies move through crowd-control zones.
- Auxiliary Support: Add supporting units only after primary damage towers are fully upgraded and covering key track segments.
Economic Strategy and Upgrades
To afford high-tier upgrades in late waves, establish an economic foundation early in the run:
| Phase | Economic Focus | Upgrade Strategy |
|---|---|---|
| Early Waves | Economy & Interest Towers | Invest in income sources; place base units to survive initial waves. |
| Mid Game (Waves 50–70) | Reinvesting Savings | Sell early filler towers; fully upgrade core central DPS towers to maximum level. |
| Late Game (Waves 70–80) | Targeted Adjustments | Shift gold into AoE damage if single-target units fail to clear groups before the exit. |
Fully upgrading a small group of primary DPS units delivers higher effective damage than spreading gold across numerous base-level units. If enemies remain in your central damage zone for more than a few seconds, redirect remaining income directly into damage upgrades.
Wave Transition Milestones
Managing board composition through key difficulty spikes prevents late-wave failures:
- Wave 50: Review your board layout. Sell off early filler towers to recover gold and free up space for stronger mid-to-late-game units.
- Wave 70: Watch for high-health enemies testing single-target damage output. If mob density overwhelms your central hub, pivot saved gold into area-of-effect (AoE) upgrades.
- Wave 80: Maintain tight board density with fully upgraded core DPS towers supported by frontline crowd control.

This guide answered the exact question I had.
I wish I had read this before upgrading the wrong thing.
I tried this today and it worked better than my old setup.
Nice guide. I am checking the other Coop TD: Together articles next.
