Frequently Asked Questions
What is Build a Bunker on Roblox?
Build a Bunker is a Roblox survival experience where you loot a surface town, upgrade an underground bunker, fight mutants and raiders, and race home before nuclear blasts hit. Progress persists through room upgrades and stored gear.
Are there any working codes right now?
No active codes are verified at this time. Check our codes page after major updates — we only list codes we have tested ourselves.
What should I do first as a new player?
Read how to play, learn controls, build a sell room, and practice short loot routes with the nuke timer running.
Which bunker room is highest priority?
Most players rush sell room for income, then power room for upgrades. See the full room tier list and room priority guide for staged orders.
How do I survive nuclear radiation?
Watch in-game warnings, sync our nuke timer tool, and enter your bunker before the final phase. Full rules are in survive nuclear blasts.
Where are the best shops and loot spots?
The commercial strip has gun shops and pharmacies; industrial zones drop materials. Start with town overview and shop locations, then plan paths in the loot route planner.
Is Build a Bunker better solo or with friends?
Both work. Solos run quieter routes; squads handle revives and overwatch. Read multiplayer survival for role splits.
Are scripts safe to use?
No. Features like loot teleport, auto farm, fly, and noclip violate Roblox Terms of Service and risk permanent bans. Use our guides and tools instead — see scripts for details.
When is Krush Gladiator available?
During scheduled event windows announced in-game. Check Krush Gladiator and farm scraps for loadouts and rewards.
