Throughout Resident Evil 3 Remake, you'll come across a number of obstacles that will stop you from progressing. In most cases, you'll simply need to find a key item to open a particular door, but sometimes you'll have to solve a small puzzle or challenge.

An old friend from the Police Station that we already saw in the Resident Evil 2 remake makes a return, although it's a little simpler this time. There are no missing keys, so you only need to enter the following combinations:
Shortly after entering the hospital's underground facility, you'll need to find three fuses to continue. Here's how it works: the video is above, while the map and instructions are below. Bear in mind that the area is crawling with enemies, and there are also several items you may want to pick up along the way.
In NEST 2, after placing the Vaccine Base in the machine, you'll need to solve a ratio puzzle to complete it. The solution is as follows:
