Commanders System

Commanders are unique NPC units introduced in the recent update (alongside Downtown expansion and higher rebirth tiers). They provide passive and active buffs to your nuclear facility.

Unlike standard nukes (which you merge and launch for one-time damage), commanders stay on your plot or offer global bonuses.

1. How to Unlock Commanders

  • Participate in "boss fight" mechanics.
  • Commander boats spawn in the central water area or near the new Downtown zone.
  • Launch nukes at the boats to deplete their health.
  • The player who lands the final blow (or contributes the most damage) typically earns the commander.
  • Competition is fierce — use high-tier nukes to secure kills.

3. Commanders & Rebirth Interaction (Critical)

Commanders are permanent unlocks.

  • Rebirth resets nukes, cash, and upgrades.
  • Commanders and their upgrade levels persist through rebirth.
  • This makes them extremely valuable for speeding up early and mid-game progression after a reset.
  • As you progress through more rebirths, you unlock additional equip slots to run multiple commanders simultaneously (stacking buffs).

Notes on Synergies:

  • Sovereign is the core of almost every strong loadout due to its Legendary damage buff and auto-city attack.
  • More rebirths = more equip slots → better stacking of synergies.
  • Commanders persist through rebirths, making early acquisition highly valuable.

Merging System and Nuke Tiers

Merging is the heart of the game. Buy a bomb from the shop, place it on your grid, then drop a second identical bomb next to it. The two fuse into a single higher-tier nuke that earns more Cash per second than the two pieces did separately.

The tier ladder runs from D-tier starter bombs up through C, B, and A-tier merged nukes, topping out at the S-tier Mega Nuke. Each step up is a meaningful jump in income, so the goal is to keep feeding duplicates into the chain rather than letting low-tier bombs pile up.

You can obtain better nukes by merging two missiles of the same tier. Repeating this process continuously unlocks higher-tier missiles that generate more income and deal greater damage.

1. Tier Roles (Approximate)

  • D-tier: Starter bomb / basic nuke. Cheap merge fodder.
  • C-tier: Basic merged nuke. First real income bump.
  • B-tier: Mid-tier merged nuke. Enough income to start raiding.
  • A-tier: Advanced merged nuke. Strong offline earner.
  • S-tier (Mega Nuke): Top-tier payout.

Keep merging constantly. Avoid piling up low-tier nukes on your base. Continuous merging helps you unlock stronger missiles faster than other players.


Passive Cash and Offline Earnings

Every nuke on your grid pays out Cash per second, and that income never stops. It keeps stacking while you are offline, so you will log back in to a fat pile waiting to be collected and reinvested.

This is why merging up matters so much. A single A-tier nuke can out-earn a grid crammed with C-tier ones.

Every missile placed on your island generates money over time. Higher-tier nukes provide greater income.

Place merged nukes on your base so they generate passive cash over time based on their tier, then collect this income regularly to fund future upgrades. Earn passive cash every second, including offline cash while away from the game.


Raiding and Base Defense (Lock Base)

Once your income is stable, you can raid other players to steal their Cash. Raids are the fastest way to spike your balance, but they cut both ways.

The base lock is your only real defense. Lock it before you go raiding and before you close the game. You will face a 30 second cooldown between two base locks.

Raids reward you with a chunk of the target's Cash. A good rule of thumb: never carry so much uncollected Cash that one bad raid wipes out an hour of merging. Collect, reinvest, lock, then go hunting.

Pick soft targets for early raids. Always lock up before logging off.


Rebirth System (Advanced Mechanics)

Rebirthing resets your nukes, cash, and upgrades but rewards you with permanent money multipliers and access to stronger nukes for future runs.

Rebirths unlock permanent money multipliers and stronger nukes for long-term scaling.

1. Rebirth 5 Threshold (Current Major Gate)

  • Reach a Tier 30 nuke with an exact value of 536,870,912 (2^29).
  • Produced by merging two Tier 29 nukes (268M each).
  • Manual grind: 8–12 hours. With Auto Merge: 3–5 hours.

2. What Resets

  • Nukes on grid
  • Cash balance
  • Upgrades (Spawn Tier, Max Spawn, Lock Base)

3. What Persists / Is Gained

  • Permanent Cash Multipliers (stack multiplicatively)
  • Access to stronger starting nukes in new runs
  • Commanders and their upgrade levels (very important)

Rebirth Cap: Currently 5 (with Rebirth 6 mentioned in newer updates).

4. Optimal Rebirth Strategy

Do not rebirth too early. Wait until you have cleared enough missile tiers and built a solid base.

Best Advanced Timing:

  1. Push to Tier 30 nuke.
  2. Participate in City Events.
  3. Use high-tier nukes on the city for massive cash (6–7 Quantillion per strong strike reported).
  4. Rebirth immediately after big city payouts.

This timing allows you to carry huge cash advantages into the new run.

Rebirth 5 + x2 Spawn Speed is considered a strong late-game position.


Sovereign - Detailed Breakdown (Legendary Commander)

Sovereign is widely considered the best and most powerful commander in the current update (S-Tier / "undisputed king").

1. Key Mechanics & Abilities (Detailed)

1. Global Damage Buff

  • Provides a flat +15% nuke damage to all your nukes.
  • This is a global multiplier that applies to both player bases and city event damage.
  • Stacks with other buffs (e.g., from Siege Breaker or Gunner).

2. Auto-Attack City Events (Passive Income Core)

  • While equipped and active, Sovereign automatically targets and fires at active city/Downtown events.
  • Generates passive cash income from city destruction without manual intervention.
  • Player reports indicate the auto-attack works best when the player remains somewhat active in the session (not fully AFK for long periods).
  • Provides "bonus to event" cash multipliers, making it one of the strongest tools for endgame farming.

3. City Event Synergy

  • Significantly increases cash gains from city events (reported as one of the fastest ways to make money).
  • Works especially well during city events that appear periodically (e.g., every ~50 minutes in some sessions).
  • The combination of +15% damage + auto-attacks allows massive passive accumulation.

4. Acquisition & Boss Fight Mechanics

  • Spawns as a Legendary boss boat in the water/Downtown area.
  • Estimated HP: 150,000+ (very high).
  • Requires high-tier nukes (Septilian damage range recommended) to reliably secure the kill.
  • Extremely contested — other players will try to snipe the final blow.
  • Best obtained in private servers or during low-population times.

5. Upgrade Path

  • After unlocking, upgrade Sovereign using cash earned from city destruction.
  • Higher levels improve the effectiveness of its auto-attack and cash bonuses.

2. Strategic Value & Playstyles

  • Best for: Endgame, AFK/passive farming, city destruction, and leaderboard climbing.
  • One of the best tools for generating cash while focused on other activities (raiding, merging, etc.).
  • Pairs extremely well with:
    • Engineer: Auto-upgrades nukes while Sovereign farms cash.
    • Spotter: Multiplies cash from hits.
    • Salvager: Keeps the plot clean.

3. Synergy with Rebirth (Important)

  • Commanders persist through rebirths (including Sovereign and its upgrade level).
  • Acquiring Sovereign before a rebirth gives a massive long-term advantage.
  • In new runs after rebirth, Sovereign allows quick ramp-up of city farming income thanks to its auto-attack and damage buff.
  • This makes it one of the highest priority Commanders to obtain early in high-rebirth play.

4. Player Consensus & Notes

  • Many top players describe it as "literally broken" due to the combination of global damage + automated city income.
  • It is the single best investment for late-game progression and passive wealth generation.
  • Requires some player activity to maintain optimal auto-attack performance (not 100% passive).

Summary: Sovereign transforms the game from active grinding to a hybrid active/passive experience, especially powerful when combined with other Commanders and timed with city events.


General Tips and Advanced Strategies

  • Early Game: Prioritize Spawn Tier upgrades + constant merging. Keep grid with ready merge pairs.
  • Mid Game: Balance all upgrades. Start raiding soft targets after stable income.
  • Late Game: Focus on high-tier nukes, City Events, and acquiring strong Commanders (especially Sovereign).
  • Rebirth Timing: Always try to hit big city payouts before rebirthing.
  • Commanders Priority: Sovereign > Siege Breaker / Engineer > others depending on playstyle.
  • Check in on update days (frequently Fridays) for new content.
  • Maintain a Cash buffer before big merges or expansions.

Upgrades

Over time, each nuke that is placed at your base will generate some income based on their tier. You can spend this money to execute the following upgrades:

  • Spawn Tier: Enhance the level of each spawning nuke. Higher-tier nukes generate more income and reduce the number of merges needed. Purchase early.
  • Max Spawn: Increase the carrying capacity of your base. More nukes = more passive income.
  • Lock Base: Increase the duration of the protective shield.

Balance upgrades. Spending all your money on a single category can slow overall growth.
