Resident Evil 4 Remake’s Power Puzzles May Seem Complex, But These Solutions Make Them Simple

In the Resident Evil 4 remake, there are mini-games called Electronic Lock Terminals, often referred to by players as power puzzles. To solve them, move the red cursor and press the interact button to rotate the switches until the current flows in the correct direction and powers the batteries.

There are three Electronic Lock Terminal puzzles in Resident Evil 4, all located in the Facility area of the Island map: One is in the Dissection zone, another can be found in the Freezer, and the last one is located in the Waste Disposal. The important thing to remember is that each puzzle has two different solutions: one for Assisted and Standard difficulty, and another for Hardcore and Professional difficulty.
