Charges arrive one at a time on the conveyor. Place each one where it can crack reinforced material, ignite a powder relay or connect a bigger chain. Watch the incoming debris and clear the shaft before it overflows.
Take on 24 demolition jobs across six harbor districts, from the Quay to Crownworks. Different structures combine original demolition targets, chain goals, powder crates and fixed mounts. Clear a job to unlock the next, then return for faster clears, stronger chains and all 72 mastery medals.
Earn coins through play and choose your equipment. Crane Brake pauses new debris while blasts and falling material keep moving. Remote triggers planted charges. Catch Net offers one overflow recovery without removing the original structure. Permanent Reach, Lift and rig upgrades and selectable fuse timing let you try different approaches.
Chase separate endless records in Open Shaft, Cross Braces and Steel Maze. Records distinguish equipment, tool use and rescued runs so you can compare like with like.
Core campaign attempts and retries are free. Local progress and earned equipment work offline. Optional rewarded ads provide the stated bonus when available. Factory Pass removes automatic ads; optional rewarded offers remain. Purchases require Google Play, a connection and verified completion. Restoring ownership does not refill spent coins or tools.
Privacy controls, optional statistics choices, account-data deletion instructions and software notices are available in the game.
Plant charges, link explosive chains and clear 24 harbor demolition jobs.
