There are some bugs that can make its way to Fortnite with the new updates and it looks like there is a new bug that has been found where players are able to shoot through the gaps of brick walls. It is only possible to shoot through the gaps when you edit a window into a brick wall and it seems as though players will be able to use any gun to shoot through, as long as they get the right angle. This bug can be seen in a video posted on Reddit by u/squrilboy below:
You can shoot through the cracks of brick walls now from FortNiteBR
Looks like you will need to take care when you see a player edit a window into a brick wall as they can shoot you from any gap they can find. This bug gives players an unfair advantage and needs to be fixed ASAP.
This bug has not been addressed by Epic yet, but we will keep you updated with the latest.
