Beneath the Wall is the point where Industria II stops feeling like a straight narrative FPS and starts acting like survival horror. Most of the frustration here comes from solving the two puzzles under pressure and from wasting close-range ammo before the Brute, not from the corridor enemies themselves. Get those two things right and the chapter is far more controlled than its atmosphere suggests.
Chapter 2 is the middle stretch of a compact three-chapter game. If you skipped straight here, the Chapter 1 walkthrough covers the bolt cutters and crafting loop you carry into the Wall.
Beneath the Wall opens immediately after Chapter 1 closes. You exit a building and follow the path toward the ATLAS Wall—Nordman’s hideout is not where the chapter starts, it is something you discover later, once you are climbing through the Wall and past the floor-tile puzzle. When you reach it, enter the hideout on the left and search it fully. This is where you secure the SMG, so do not treat it as a story room and walk on.
Keep the bolt-action rifle as your default weapon for the Wall interiors. Enemies here appear down lanes, catwalks, and machine corridors where precision saves resources, and the SMG works better as a recovery tool when a fight gets messy than as your answer to every room. Spend crafting materials on healing and rifle ammo before anything else.
Save Point you find, even after a short section.The control panel routes power, and the mechanism only lets you keep three buttons active at once, so you solve it in two passes. On the first interaction, press all three buttons in the third row and follow the path that opens—this routes power up toward the upper-left area. On the second interaction, deselect that third row first, then select the only two buttons in the rightmost column to open the next path.
Clear nearby enemies before you start. After both routings, you also insert a collected item into the slot on the left to finish powering the section. The chapter likes to make a quiet room feel urgent, but the panel is a fixed sequence, not a guessing game—run the two passes and move on.

The pipe puzzle comes in two physical placements. First, take the loose pipe object and fit it into the opposite circuit to open the door. At the second instance, interact with the pipe-like object ahead and throw it down, then connect the pipes to the circuits. The key step players miss is the module: take it out from the left side and place it on the circuit on the north side to complete the connection.
Once the circuits are assembled, there is a Fabricator on the right side—upgrade your weapons here before pushing on. This is the right spot to spend, not Nordman’s hideout. If your healing is already stable, put the upgrade toward the rifle, which carries you through the Brute fight ahead.

The Brute waits in the underground area after the circuits are assembled, and the fight has a clear loop rather than being a raw damage race. Your main goal is to shoot the parts that glow yellow. When the Brute is glowing, hit those weak points; when nothing is glowing, take cover, switch to the shotgun, and chip it down—the pistol works for this too if you are tight on shells.
Use the environment. Lure the Brute toward the TNT and shoot the barrel for a large chunk of damage. The boss will also try to take cover inside a cage, and when its cage rises it regenerates some of its parts, so you simply repeat the process: expose the glowing parts, punish them, and force it back out.

Manage the adds. Other enemies appear during the fight and keep coming, so clear them before you go back to shooting the big robot—getting flanked while you line up a weak-point shot is what actually ends most attempts. Heal after you have created distance, not the instant you take a hit.
Once the Brute is down, the chapter is mostly cleanup. Reload, grab any remaining supplies, then enter the vehicle to return home. From there you wait for Marlene and pull the lever to trigger the cutscene that ends the chapter. If a Save Point is nearby, take it before the closing beats. The story then rolls straight into the Chapter 3 walkthrough, the current endpoint of the game.
Loot Nordman’s hideout for the SMG, solve the control panel (third row, then rightmost column) and the pipe puzzle (loose pipe into the opposite circuit, module to the north side), upgrade the rifle at the Fabricator, then beat the Brute by shooting its glowing parts, baiting it onto the TNT, and clearing adds between phases. Do that and Beneath the Wall is a clean run to the ending cutscene.
