The Scrapyard is the next area after the Sewers. The general layout of the area is a mix of the open parts from the Desert, and the constricted corridors from the Sewers. It rains constantly in the Scrapyard, a depressing indication of the challenge to come.
The Scrapyard is filled with cars that explode when shot the requisite amount of times. This can be helpful in taking out large groups of enemies, but also quite dangerous if used for cover. A Proto Statue will spawn in 3-2.
The enemy number seems to almost double compared to past areas. The Scrapyard leads to the Crystal Caves.
