To clear Deepsea mode in Coop TD: Together using an eight-unit constraint, each player must limit their board to exactly eight towers, including a single Clara. Success relies on placing Clara where her radius hits the enemy path while buffing adjacent units, then investing all gold into upgrading those eight towers rather than expanding your board.
Slot Allocation and Setup Strategy
Because each player uses only eight slots (creating a combined board of 16 units), every unit must fulfill a strict role. Avoid buying unnecessary early-game towers that do not scale into late waves.
| Slot Priority | Unit Focus | Required Function |
|---|---|---|
| Hero (1 Slot) | Clara | Core anchor; provides path coverage and proximity buffs to nearby towers. |
| Primary DPS (1–2 Slots) | High-scaling Damage Dealers | Concentrated damage output aimed at clearing bosses and tough waves. |
| Control (2 Slots) | Slows or Stuns | Locks enemies inside Clara's effective area to maximize damage windows. |
| Support (3–4 Slots) | Stat Buffs / Utility | Amplifies primary damage dealers and strips enemy armor in late waves. |
Clara Positioning Rules
Clara's placement dictates the performance of the entire defense:
- Place Clara at a central intersection or main bend. This ensures her abilities cover the path while keeping surrounding tiles open for your primary damage towers.
- Surround Clara with primary DPS units. Position your main damage dealers directly adjacent to Clara so they benefit from her proximity buffs.
- Avoid the extreme front or back lines. Placing Clara too close to the enemy spawn risks leaking fast enemies early, while putting her too far back prevents her from hitting waves before they overwhelm your front line.
Upgrades and Partner Coordination
Once your eight slots are filled, stop purchasing extra units and adjust your economy:
- Pivoting is restricted: Minimalist builds have little room for error. Decide your unit roles early and commit gold strictly to leveling up established towers.
- Coordinate team roles: Communicate with your partner before spending gold. One player can carry heavier crowd control while the other emphasizes single-target damage or armor reduction. Avoid building identical setups that duplicate utility without increasing raw damage output.
- Push percentage upgrades: In the final waves of Deepsea mode, focus entirely on upgrade thresholds that grant direct damage multipliers to your core DPS towers.

Nice guide. I am checking the other Coop TD: Together articles next.
This helped me understand strategy much better.
This saved me time in the early game.
The explanation is clear, especially for beginners.
