3. After powering up the generator, you will be assigned to gather 3 TNT sticks. And of course, they will be hidden in one of the 5 spots gas tanks can be hidden.
4. After placing all TNT sticks in the box, you must step on the igniter. Once all the blocks from the brick wall have cleared, head into the upper room. There you must once again collect 5 items which will be on the shelves.
5. And finally, after gathering all said items, it is time to run for rescue. Run right back to the area you first spawned in. It's best to close the blast door right after all your teammates have made it through. And now hop onboard the boat for your cash prize.
