Your first moves after spawning
Step
Zombies start approaching early, so your bunker needs walls before you spend time doing anything else. Once you have a basic defensive perimeter in place, you can safely begin exploring the map for wood, metal, and food. Survivors you meet out there can be brought back to the bunker, which strengthens your team from the very beginning.
- Build the walls place building parts around the bunker to stop zombies from walking straight in.
- Scan the area nearby look for resource points close to the bunker before wandering far.
- Rescue any survivors you find bring them back to the bunker so your team starts growing.
- Upgrade your defenses spend the resources you collected on improving the bunker's strength and features.
Layered bunker design
TipsA single wall will not hold forever as zombie waves get harder. The most effective approach is to build outward layers of walls so zombies have to break through more than one barrier before reaching you. Building parts cost resources, so plan regular exploration runs to keep your supply topped up.
- Stack multiple wall layers so zombies cannot break through everything at once.
- Place watchtowers at height to spot incoming zombies early.
- Schedule exploration trips to restock building materials before you run short.
Rescued survivors and their training
Check
When you find a survivor on the map, getting them back to the bunker is just the start. Training is what actually makes them worth having: higher training levels mean they will fight back automatically when zombies attack, which takes real pressure off your defenses. Training costs resources, so keep enough in reserve to keep the process going.
- Confirm how many survivors are currently in the bunker more members means stronger overall defense.
- Check each survivor's training progress so nobody is left at a low level by accident.
- Make sure you have enough resources on hand to keep training running continuously.
- Review where survivors are stationed inside the bunker and move them to more useful positions if needed.
Exploration and resource collection
TipsExploring carefully during the gaps between waves lets you cover more ground without getting caught in a fight. Food is worth collecting consistently because survivors need it.
- Search every corner of the map rather than sticking to the same spots.
- Head deeper into the map for rare items — they are not found close to the starting area.
- Time long exploration runs for the quieter periods between zombie waves.
- Collect food regularly to keep up with what your survivors need.
Keeping up with escalating waves
WarnAs the game goes on, zombie attacks become more numerous and more dangerous. Defenses that were enough to survive the early days will start to crack under the pressure of later waves. The key is to treat upgrading as an ongoing task rather than something you finish once and forget. Watch for signs that a wave is about to intensify, and do not leave broken parts of the bunker unrepaired.

Common questions
FAQWhat happens if zombies break through my bunker?
If the zombies overrun your bunker, the game ends. Surviving as many days as possible before that happens is the whole point of the game.
How do I collect resources safely?
Head out to explore the map and pick up wood, metal, food, and other materials you find scattered around. The safest time to go is during the quieter gap between zombie waves, especially if you plan to travel far from the bunker.
Do I need to spend Robux to have a strong base?
No — the game is designed so that free players can build a fully capable bunker through regular play. Paid options can speed up progress, but consistent resource gathering and upgrading gets you to the same place without spending anything.
