Zero City: Zombie Shelter Game - How to Get 5-Star Dwellers

The fastest and most reliable way to obtain 5-star dwellers in Zero City: Zombie Shelter Game is to farm Dog Tags during the weekly Tunnels event and buy dwellers directly from the Tunnels store. This method removes reliance on standard breeding RNG or spending premium currency.

The Weekly Tunnels Schedule

The Tunnels event follows a weekly cycle that begins every Friday. Because Dog Tags are tied specifically to this event, active play during the weekend is required to collect enough currency.

• Event Start: Every Friday.
• Core Loop: Clear Tunnels stages to gain event currency before the shop inventory and event reset.
• Goal: Stockpile enough Dog Tags to buy high-star citizens during the event window.

How to Farm Dog Tags Efficiently

You earn Dog Tags by progressing through Tunnels stages and completing objectives. To maximize your earning rate:

1. Maintain Steady Stage Progression: Clear stages cleanly rather than burning high-value consumables on a single roadblock boss.
2. Adjust Squad Setup First: If your team stalls on a difficult stage, adjust your squad composition or upgrade equipment before re-engaging.
3. Focus on Consistency: Consistently clearing reliable stages every Friday builds the currency needed for store purchases over time.

Spending Dog Tags in the Tunnels Store

Once you save enough Dog Tags, open the Tunnels store to acquire 5-star dwellers.

• Prioritize 5-Star Dwellers: Avoid spending Dog Tags on random chests, equipment, or temporary boosters. 5-star dwellers provide permanent higher stat caps that improve long-term combat performance and resource gathering.
• Inventory Stock Limits: The Tunnels store holds a limited stock of 5-star dwellers per event cycle. Once you purchase the available stock, you must wait for the next event rotation and store reset to buy more.
