Upon exploring the areas of F.I.S.T Forged in Shadow Torch, no doubt, you'll come across metal doors that you cannot open or even destroy. Due to F.I.S.T being a Metroidvania, there will be a time where these doors can be opened.
These doors, when approached, will automatically update the map. Some will turn red and others yellow. These Red Doors with the Drill icon will be the second ones you will open. To break them, you first need to progress with the story, get inside the Power Station and acquire the Drill.
You don't need to learn any special move or anything of the sort to open the Red Doors with the Drill. All you need to do is head up to the door and press Circle or Triangle. After a small amount of time, the door will be unlocked.
Do make sure that if you find a Red Door that cannot be opened with the Drill, that it isn't the back of the door. As the Drill, very much like the Fist, can only open doors from the front. So if you come across a Red Door on the map, you may not be able to open it straight away.
