This page of our guide for Resident Evil 3 Remake contains a complete solution to the puzzle that involves restoring the power supply to the Subway Power Substation. This involves locating and using four breakers. During the task, you'll be harassed by giant spiders.
The puzzle appears shortly after reaching the Control room at the Subway Power Substation. Jill learns of the need to reach the 4 breakers in order to interact with them.
To the left of the large control panel is a new door leading to another area. You need to investigate this place and find the body with the box. In the box, you'll find a picklock.
Use the lockpick on the gate shown in the screenshot - it leads to an area with four breakers.
Before you open the gate, prepare at least 1 Green Herb. You can find some on the right side of the gate.
In addition, we suggest bringing a shotgun, which will be the best weapon to attack monsters who are interfering with the puzzle.
Spiders - how to deal with them?
Just after opening the gate, Jill is attacked by the first spider in a surprise attack and unfortunately, this cannot be prevented. The heroine becomes infected with a parasite.
Infected Jill moves very slowly, but you can cure her with the Green Herb. The heroine will thus get rid of the parasite and be able to move and run at normal speed.
Unfortunately, you're going to be harassed by more spiders when completing the puzzle. They can also re-infect Jill if they manage to jump on her.
There are two solutions to this problem - attack spiders from a greater distance or perform dodges (press R1/RB on the pad) when a spider makes a jump. This will cause him to miss and also a bullet-time will be activated, enabling you to easily kill the spider.
Against spiders, shotgun works best. Each spider should die after 1 hit, and if there were 2 spiders next to each other, they could be killed with a single shot from a shotgun.
Keep an eye out because spiders can walk on walls and ceilings. Check these places a lot so you don't get surprised. There are also small generators in the area that can electrocute nearby spiders - shoot at them from a distance so that the heroine does not get electrocuted as well.
You can find more green herbs when you reach further breakers. It's worth picking them up so that you always have at least 1 green herb prepared so you can instantly cure Jill in case she gets infected with a new parasite.
Reaching 4 breakers
The optimal route to reaching the next breakers is shown in the above map. The maze of corridors is not too complicated, as many passages are initially blocked.
- The red color marks the route to the next circuit breakers-1, 2, 3 and 4.
- The green color marks the escape route after all four breakers are activated.
Once you reach each breaker, you have to hold the interaction button for a few seconds. This, unfortunately, makes Jill an easy target for spiders. Before you start the procedure of activating the switch, first get rid of the spiders in the area. In addition, after each successful operation, quickly rotate 180 degrees so that you can fire on incoming spiders if necessary.
After activating all the switches, escape the spider area through the gate you opened earlier.
Return to the control room and watch a short cut-scene from the power restoration. All four screens should now have green lights on.
