so people on level 1 use the boxes of stuff to go on other levels and harvest things there to build custom weapons like guns

but very rarely, they can actually find guns that are from the frontrooms (the regular world), so if you want to buy things like weapons, if you have enough money, you are advised to go for the ones from the frontrooms, because the ones made in the backrooms tend to not be made by professionals, leading to them sometimes misfiring while youre bringing them out or running, or them NOT firing when you want them to. you also have to maintain them more often or else the issues i talked about above will be extremely common, so much to the point to where you give up running and instinctively spam-click your mouse when trying to shoot (also if they misfire when you bring them out, you take 1.5x the amount of damage that it regularly deals because its really close to you)
