Tunnel Hazard is one of the 15 launch minigames in Machine Party, a 2 to 4 player high-stakes party collection from developer Mike Klubnika (Buckshot Roulette) and GDeavid, published by Oro Interactive. The Steam Community achievements page is the only first-party source for the win condition, and it reads exactly: "Win by taking the last nook in Tunnel Hazard." That same sentence is the This is my hole. achievement unlock condition, with no extra round-count, survival timer, or accuracy requirement attached.
What the source actually says about Tunnel Hazard
The Steam Community achievements page is the only first-party description of Tunnel Hazard on the launch surface. The Steam store page lists Tunnel Hazard as one of the 15 achievements tied to the launch set, alongside machine names like Firearm Factory, Duck Hunt, Spinebreaker, Stable Footing, Wrong Way, and Table Manners, but it does not describe the round itself. The achievement text is the win condition and the unlock condition at the same time.
Tunnel Hazard sits inside the larger framing Mike Klubnika's developer log gives for the game: a frantic multiplayer collection where most minigames amount to short, high-stakes tests and the round-to-round pace is built so that individual challenges stay short. The developer log frames the set as a 2 to 4 player party collection cut for fast rounds, and the Steam store page carries the same mix of cooperation, competition, and betrayal framing through Gamespress and tagged features. Tunnel Hazard is part of that set, but the developer log does not name the minigame or describe its layout.
The Gamespress launch press release, Steam store, and developer log all confirm the 15-minigame set and the 2 to 4 player support, but none of them describe the tunnel layout, the number of nooks, the collapse behavior, the order in which nooks appear, or any platform-specific controls for Tunnel Hazard. Anything beyond the last-nook achievement wording is not in the current source.
How to unlock This is my hole. in Tunnel Hazard
The This is my hole. achievement is the source-bounded win condition for Tunnel Hazard, and the only first-party rule is the last nook in the round. The page keeps the walkthrough aligned with that wording only.
The win condition is the last nook, not an early one
The Steam Community achievements page condition is "Win by taking the last nook in Tunnel Hazard." The phrasing is the entire unlock rule, and the page does not invent any extra steps beyond it. The achievement fires when a player takes the last nook in the round, and no other source documents a separate survival timer, accuracy check, or round-count requirement.
The achievement condition matches the round win condition
The same sentence is both the round's win condition and the achievement's unlock condition. A player who wins the round by taking the last nook in Tunnel Hazard triggers This is my hole. on Steam, and the Steam Community achievements page does not list any additional condition such as playing in a specific lobby size, completing a set number of rounds, or finishing with a particular score. The page does not add any extra rules of its own.
Where this guide stops adding rules
Anything beyond the last-nook wording is intentionally left out. The tunnel layout, the order in which nooks appear, when the tunnel collapses, how the last nook is presented, how many nooks the round contains, and the timing a player would need to claim the last nook are not in the Steam Community achievements page, the Steam store page, the developer log, or the Gamespress launch press release. The guide does not fill in those gaps, so the This is my hole. walkthrough here stays a source-bounded summary of the achievement condition rather than a fabricated round walkthrough.
What the source does not say about Tunnel Hazard
To keep the guide source-bounded, the following items are not in the current evidence and are not invented here:
- The tunnel layout, when the tunnel collapses, or how nooks appear and disappear.
- Whether earlier nooks count toward the round or the achievement.
- How many nooks a round contains, or how the last nook is presented.
- Specific player positioning, entry order, or timing strategies.
- Whether the round behaves differently in a 2 player, 3 player, or 4 player lobby.
These are documented as unknowns rather than filled in with guessed values. The Steam Community achievements page and the Steam store page are the only official sources for Tunnel Hazard, and neither goes beyond the last-nook achievement wording as of 2026-08-09.
Where this guide sits in the 15-minigame set
The minigame is one of the 15 launch minigames in Machine Party and one of the seven with a dedicated per-game guide page on this site, alongside Firearm Factory, Duck Hunt, Spinebreaker, Stable Footing, Wrong Way, and Table Manners. The other eight minigames are listed on the minigames hub and the achievements page, where their unlock conditions live. The Steam Community achievements page confirms the 15-achievement feature row and the per-minigame naming, and the Steam store page carries the same 15-achievement count on the launch listing.
The Steam Community achievements page puts This is my hole. alongside the other 14 Steam achievements, all of which appear in the developer log and the stored launch set. The full unlock condition set sits on the achievements page of this site, and the developer log frames the 15 minigames as a single short-form party collection rather than separate single-player modes.
