Puzzles & Survival: How to Unlock the Cyborg and Farm EXP

To unlock the Cyborg in Puzzles & Survival, you must acquire and administer all four doses of the antidote to fully cure the patient in your Sanctuary’s medical facility. Once the fourth dose is applied, the infection is cleared, unlocking the Cyborg's EXP progression bar and passive talent branches.

How to Unlock the Cyborg

Unlocking the Cyborg is tied directly to early base development and campaign progression. The unit remains locked in the medical facility until the four-stage treatment is complete.

1. Complete chapter quests and Sanctuary tasks: The four antidote doses are earned by clearing core campaign milestones and early development objectives.
2. Access the medical facility: Navigate to the medical building inside your Sanctuary whenever an antidote dose is awarded.
3. Administer the treatment: Apply each dose as you receive it to lower the patient's infection level.
4. Finalize the cure: Administer the fourth dose to trigger full recovery. This activates the Cyborg as a permanent support system and unlocks its skill trees.

Best Sources for Farming Cyborg EXP

Once unlocked, the Cyborg requires dedicated EXP to gain levels and earn skill points. Repeatable daily PvE tasks and Alliance activities offer the most reliable EXP income.

Daily EXP Farming Routine

• Join Alliance Zombie Lair rallies: Rallies against Zombie Lairs provide the highest return on stamina for Cyborg EXP. Join high-level rallies started by stronger Alliance members using the 1-troop join method to conserve your army while earning full completion rewards.
• Reach the 150-point Daily Quest chest: Clear routine tasks each reset—such as resource gathering, building upgrades, and arena matches—to hit the 150-point milestone chest, which contains guaranteed EXP caches and stamina items.
• Push PvE Campaign stages: Whenever your troop tier increases or combat stats jump from upgraded gear, clear higher Campaign and Trial stages to collect one-time EXP milestones.

Allocating Cyborg Skill Points: Military vs. Economy

Each level threshold grants skill points that can be spent in either the Military or Economy branch.

• Economy Branch: Focuses on Construction Speed, Research Speed, and Resource Gathering Rates. Invest your initial points here during the early development phase to shorten building and tech timers for your Sanctuary.
• Military Branch: Boosts Troop March Capacity, individual troop attack (Riders, Shooters, or Fighters), and base defense. Troop March Capacity is the highest-value military stat because larger armies deal significantly more damage in rallies.
• Specialize your military investment: Avoid distributing combat points evenly across all three unit types. Invest strictly in the specific troop type that matches your primary hero lineup and gear focus.

Once your core infrastructure reaches high levels, you can reallocate points from Economy to Military ahead of major competitive warfare events.
