"Halo 3" contains non-gameplay additions, such as Forge, a map-editing tool. Forge enables players to insert and remove game objects, such as weapons, crates and vehicles into existing multiplayer maps. Almost all weapons, vehicles, and interactive objects can be placed and moved on maps with Forge. Players can enter Forge games and edit and manipulate objects in real time. A budget limits the number of objects that can be placed. Players may also save up to 100 films of gameplay to their Xbox 360's hard drive, viewing the action from any angle and at different speeds. "Halo 3" offers a form of file sharing, where items such as saved films, screenshots, and custom variants can all be uploaded to Bungie's official website. Anyone can browse user created content that has been uploaded to Bungie's website and tag it to automatically download to their console next time they sign into Xbox Live on "Halo 3".
