Practice before collecting a bomb
Enter the TOPFUN van to control the RC Goblin. The countdown starts when you first collect a bomb, so use the untimed opening to learn lift, steering and dropping controls. Fly through the central stairwell and locate all four target floors. Each control scheme is different: read the in-game prompts rather than using a keyboard instruction on a controller.
- Keep the helicopter clear of walls and ceilings.
- Carry one bomb at a time and use the target markers to judge drop height.
- A failed placement can be collected and tried again.
Keep a repeatable route
You can place the charges in any order. A top-floor-first route lets you work downward, but consistency matters more than a claimed universal fastest path. Return smoothly for each bomb instead of taking risky cuts. The standard mission gives seven minutes after the first pickup; some mobile versions use a different timer. This Avery mission is optional for the main ending, but required for 100%.
