When you trigger a Build a Military Base rebirth, your entire base resets. Every structure, weapon, and Tycoon unit你必须 repurchase. But here's why it's worth it: each rebirth permanently increases your Cash Bonus from workers by ×0.1, stacking up to ×5 at Rebirth 40. Plus, higher rebirths unlock exclusive vehicles, weapons, and defenses you cannot get any other way.
This guide breaks down every Build a Military Base rebirth reward, tier by tier. Whether you are aiming for the Railgun at Rebirth 25 or the final ×5 multiplier at Rebirth 40, we have you covered.
How the Rebirth System Works
Before diving into the rewards, you need to understand the mechanics. Initiating a Build a Military Base rebirth resets your progress, but not everything is lost:
- What resets: All base structures, weapons, gear, and Tycoon units must be repurchased.
- What carries over: Buildable units, Event units, and Gamepass units are permanently kept.
- Diamond Generators: These pause production during a rebirth until you repurchase the Hatch and re-enter the Vault Room.
- Bunker Access: You must repurchase all Workers in the huts to regain entry.
There is no cap on total rebirths, but the meaningful rewards stop at Rebirth 40—making that the true endgame target.

Pro Tips for Efficient Rebirths
Reaching Rebirth 40 requires strategy, not just grinding. Here are expert recommendations:
Prioritize Permanent Units
Since Buildable, Event, and Gamepass units survive each Build a Military Base rebirth, invest in these early. They provide consistent firepower while you rebuild your base from scratch.
Time Your Rebirths
Don't rebirth the moment it becomes available. Wait until you have enough resources to quickly repurchase key structures like the Vault and Bunker. Diamond production pauses during rebirths, so minimize downtime.
Focus on Cash Bonus
Each Build a Military Base rebirth adds a ×0.1 multiplier to worker Cash production. Early rebirths feel slow, but the exponential growth makes later runs significantly faster. Push through the early tiers to unlock the snowball effect.
Unlock Vehicles Strategically
Some vehicles are locked behind specific rebirth tiers. If you need a particular vehicle for defense or resource gathering, check the list above and target that rebirth milestone first.
Frequently Asked Questions
Is there a limit to rebirths?
No. You can rebirth infinitely, but all meaningful unlocks stop at Rebirth 40. Beyond that, you only gain the ×0.1 Cash Bonus per rebirth—which caps at ×5 anyway.
Do I lose my Diamonds when I rebirth?
No, but your Diamond Generators pause production until you repurchase the Hatch and re-enter the Vault Room. Always withdraw your Diamonds before rebirthing if you plan to be offline for a while.
What is the fastest way to reach Rebirth 40?
Focus on cash generation first. Upgrade your workers and bunker early. Use permanent units (Buildable/Event/Gamepass) to defend while you rebuild. Every Build a Military Base rebirth makes the next one faster due to the Cash Bonus multiplier.
Can I access the Bunker immediately after rebirthing?
No. You must repurchase all Workers in the huts first. The Bunker is locked until then, so prioritize worker huts early in each rebirth cycle.
