Coop TD: Together Abyss Carry: Coin Man and Goblin Biker

To carry Abyss mode encounters in Coop TD: Together using this combination, bring both Coin Man and Goblin Biker to at least Level 11 (+2) with Liberation 10. This pairing functions as a self-sustaining economy engine: Coin Man generates the high gold output required to continuously fund upgrades, while Goblin Biker consumes that capital to provide the raw frontline DPS needed to clear high-health enemy waves.

Unit Roles and Investment Thresholds

Reaching the Level 11 (+2) and Liberation 10 benchmarks on both units is essential before relying on them as your primary carry setup in Abyss mode. Lower investment levels leave your economy scaling too slowly or leave your damage output unable to keep pace with late-wave health pools.

Unit	Primary Function	Key Requirement	Strategic Focus
Coin Man	Economy Engine	Level 11+2, Liberation 10	Early gold generation to fund mid-to-late game upgrades
Goblin Biker	Main DPS Carry	Level 11+2, Liberation 10	Target clear against dense groups and armored enemies

Coin Man: Upgrade Coin Man as early as wave difficulty allows. Generating excess gold early lets you deploy and maximize secondary towers without risking your defense during sudden difficulty spikes or boss spawns.
Goblin Biker: Use the gold pool created by Coin Man to aggressively level up the Biker. Its high scaling ensures it can handle high-density monster packs that standard defensive options fail to clear.

Unit Placement and Trade-Offs

Maximizing this strategy requires careful board management and positioning adjustments:

Position Coin Man in safe zones: Place Coin Man away from immediate danger and core paths to keep its income-generating mechanic running continuously.
Position Goblin Biker at chokepoints: Place the Biker along primary path intersections or key chokepoints to ensure full attack coverage across incoming waves.
Account for reduced utility: Dedicating board slots to Coin Man limits space for crowd-control or slowing towers. You must rely on the Biker's high raw damage output to eliminate enemies before they pass your chokepoints.
