Crystal Maze sends Trevor to the O’Neil farm after the Cheng representatives choose another supplier. The objective is to clear a path into the farmhouse, reach the basement laboratory and ignite a fuel trail. Gold rewards precision: careless spraying and a rushed entry make the accuracy and damage targets harder.
Step-by-step walkthrough
-
Survey the farm from the hillside
Drive to the marked vantage point overlooking the property. Use a scoped rifle to identify exposed defenders before moving downhill. Look for two enemies standing in line and take a single shot through both for 2 Birds 1 Stone.
Do not assume that two quick kills count. The requirement is two enemies killed by the same bullet. If the pair moves out of alignment, wait for a better angle rather than firing repeated speculative shots.
-
Clear the yard before entering
Work through the outdoor guards from cover and use deliberate headshots towards the total of ten. Keep track of enemies near doors, vehicles and the side of the house. Trevor’s special ability can protect an exposed move, but a controlled approach is still better for the accuracy objective.
Move closer only when the near side is clear. Charging directly across the yard allows enemies outside and inside the farmhouse to shoot at the same time. Missed bursts also reduce the percentage needed for gold.
Use the elevated approach to line up accurate shots before entering the farmhouse. -
Sweep the farmhouse and reach the basement
Approach an entrance with your weapon ready and clear each room before crossing it. Check doorways and corners rather than standing in the middle of the corridor to trade shots. Follow the objective towards the basement once the route is safe.
Deal with the remaining defender in the laboratory. Do not start focusing on the fuel objective while an enemy still has a clear shot. This last indoor section can undo an otherwise careful Unmarked attempt.
-
Lay a continuous trail and ignite it from safety
Pick up the petrol can and pour fuel along the marked route out of the laboratory and towards the exterior. Keep the trail connected; disconnected patches can prevent the fire travelling back to the target.
Once outside and clear of the fuel, ignite the trail with a shot and let it burn towards the building. Move away from the explosion, take the escape vehicle indicated by the mission and leave the area to complete the job. The final spectacle is not an invitation to stand beside the house.
Gold medal checklist
- Headshots: Kill ten enemies with headshots. Use the hillside and controlled indoor shots.
- Unmarked: Finish with minimal damage to health and armour. Clear the yard before entering.
- 2 Birds 1 Stone: Kill two enemies with one shot. Line up two defenders with the sniper rifle.
- Accuracy: Finish with at least 80% shooting accuracy. Avoid speculative bursts and unnecessary shots.
Common questions
Is there a gold time limit?
No timed objective appears in this mission’s gold checklist. Take time to line up the two-enemy shot and preserve accuracy.
Why will the laboratory not explode?
Check that the poured fuel forms a connected route from the basement to the ignition point. Follow the mission’s marked path and ignite the fuel from outside.
