To complete Deepsea runs in Coop TD: Together, set up low-cost defensive units early, place area-of-effect support towers on central tiles, and reserve chokepoints for single-target damage dealers. Maintaining a gold buffer protects against unexpected boss spawns, while selling low-tier units late in the run opens board space for high-tier upgrades.
Optimal Board Positioning by Tile Role
Assign your towers to specific tiles based on their operational focus to keep mobs from breaching your lane.
| Tile Location | Unit Type | Primary Defensive Role |
|---|---|---|
| Central Tiles | Support Units | Overlap area-of-effect buffs across your main damage towers. |
| Chokepoints | Single-Target DPS | Focus high damage on bosses and high-health targets where enemies slow down. |
| Backline | Auxiliary Damage | Intercept stray mobs that breach your primary defensive zone. |
Early-Game Setup and Gold Flow
- Deploy Low-Cost Defenses First: Place low-cost, high-efficiency towers during the initial waves to stabilize your lane without draining your funds.
- Establish the Kill Zone: Transition into your primary damage units once early waves are secure, concentrating your main damage output around key chokepoints.
- Maintain a Gold Buffer: Keep a reserve of gold rather than immediately spending all earnings. Use this buffer to perform emergency tower replacements or react to sudden difficulty spikes.
- Time Your Upgrade Spending: Reinvest in damage stat upgrades only when your current setup clears incoming waves comfortably. Delay minor static additions to save for major upgrade tiers.
Adapting to Dense Waves and Bosses
- High-Density Waves: Shift your focus toward splash damage or chain-attack towers to clear massed enemy groups before they overlap.
- Boss Waves: Concentrate single-target damage output directly on chokepoint tiles so bosses take maximum damage before reaching the end of the track.
- Late-Game Board Transitions: Sell lower-tier towers to free up space for high-tier units only when you are certain your remaining board state can handle ongoing wave pressure.
