Gun uploads generally receive a modest to low amount of votes, simply due to their relative-unoriginality, and simplicity. Sometimes, users upload large compilations of different types of guns separated by block boarders that can be activated by the viewer. In certain uploads, the player can can copy and paste guns and other tools into a player course. Most guns are single-use technologies, and must be reloaded with the save-load feature, or even require new ammunition to be copy and pasted into the chamber by the player. However, some guns use clone to replace the propellant and ammunition to create an auto-reloading gun.
