How to Hide Underground in Bunker vs Verity

Bunker vs Verity advertises a simple escape hatch: "🚪 Hide underground when things get crazy". What the game does not give you is a secret bunker waiting somewhere on the map, a hide button, or a teleport. The underground hideout is a room you dig out beneath your own bunker. You open the bunker's door, dig down, expand the space until you can walk around in it, and seal it with doors and tough blocks. During a raid, that room is where you regroup while your turrets keep working upstairs.

Treat it as a retreat, not immunity. As waves climb, some Verities can dig, and players have watched entire waves tunnel into their underground rooms. Build the route, reinforce it, and keep your weapon ready.

Dig out your underground room

The only prerequisite is a standing bunker with a working entrance — if you are still staring at an empty plot, the bunker building guide and the beginner guide get you there first. Then:

1. Open the bunker door. A full walkthrough of the game starts the dig by opening the bunker's door first, and the in-game tutorial points you the same way.
2. Dig down. In one complete guide to the game, the player presses 2 to dig and starts carving straight down from inside the bunker. That keybind comes from a PC run, so confirm the dig control in your own tutorial if you play on mobile or console, or after an update touches controls.
3. Keep digging until it is a room. Every documented run does the same thing — "Dig deeper... So, we have to dig right now" — expanding the space until it is walkable rather than a crawlspace.
4. Confirm the success state. You should be able to step through the opening and stand in a room directly beneath your bunker. Many players then furnish it with coin farms, a bed and a table, because the space doubles as a base extension.

Seal the route before a raid hits

An underground room only helps if the way in stays yours. Three actions are proven in play:

• Place doors in the dug openings. Doors fit into gaps you leave in the dug walls. One player tests it live — can a door go here? — finds that it can, frames the doorway with blocks so it sits properly, and ends the run with two bunker doors.
• Close the entrance behind you. The same full guide closes the bunker immediately after heading down. Break-in pressure through doors is real: when a defense line fails, players expect Verities to come through the bunker door, and one run shows a base door getting forced open mid-raid.
• Reinforce the shell with high-HP blocks. Late in one run, the player blocks off his bunker with Verity blocks reported at 50,000 HP each — "pretty tough to break through" — and adds two doors "so the Verities, they can't break in here." Blocks at that tier cost serious money, so the coins guide and the building blocks comparison are worth a read before you shop.

Pair doors with strong blocks rather than trusting a door alone — the strongest documented setups use both.

Retreat mid-raid, then come back up

Players use the room exactly as the description promises. One creator notes early that you can flee down here whenever you feel like it; another walks below mid-raid to relax in his safe room while keeping his focus on the fight outside; a third calls the dug-out space "my getaway right now" as the raid rages overhead.

Timing matters more than speed. Retreat when your defense line is buckling or your HP is draining — one player slips through the door at the last moment of a brutal wave and survives to beat the boss. Once the pressure drops, go back up and rejoin the turret line. Hiding is a regroup, not a win condition: the wave continues above, your defenses do the work, and the waves guide and defense strategy cover the part your room cannot do.

What hiding does not protect against

• Digging Verities. In one documented run, the player first spots Verities that can dig downward, and around wave 17 the whole wave tunnels straight into his underground room — after which he calls it not safe anymore and has to fight them off inside. That is one session, not a published threshold, so treat rising waves as a reason to expect digging attempts rather than a safe-until-wave-17 rule. The Verity enemy roster and wave difficulty explain why pressure keeps climbing.
• Gaps. The same player with the two-door, Verity-block seal later finds Verities inside anyway: "They just got in somewhere and I don't know where they got in... they got in right here." Another spots an open space above his getaway room and immediately worries Verities might come up through it. One weak or missing block is enough — audit every wall, floor and ceiling section.
• Guaranteed safety. High-HP blocks and paired doors are the best resistance documented so far, but the game itself warns that the longer you survive, the harder the Verities become. Hiding reduces pressure; it does not remove the threat.
• A pre-built "secret bunker." Decorative hidden-style bases are their own creative project — see the secret bunker build page. The functional retreat mechanic is the space you dig out yourself.

Before you rely on the room in a record attempt, run one drill: start a raid you can win, head below when pressure spikes, close the door, and watch whether anything digs or squeezes in. If the room holds, you have a verified retreat; if something gets in, you found the gap on a cheap wave instead of a costly one. Then go back up, rejoin the defense, and stack the survival loop described in the survive more waves guide.
