Forge

Forge is a Halo 3 gameplay mode that allows for both playing and designing multiplayer maps.

Background
A multiplayer-only tool, Forge will allow players to customize multiplayer maps, changing and resetting spawn points, weapon spawns, weapon timers, vehicle spawns and timers, vehicle spawn points, and add existing geometry to the map’s existing structure in the form of crates, boxes, fusion coils, lifts, teleporters, turrets, etc.

The amount of items you can drop is regulated by an economy budget system, with different items having different values and each map having an overall budget that the items you place cannot exceed. By deleting existing things off of a given map, you can actually place more things. Players can modify and create their versions of maps, save them and share them with their friends, but that’s only half or so of what Forge allows.

In addition to functioning as creation-driven tool, Forge is also a playspace. Up to eight players can be on a given map at a time, shifting back and forth between their chosen multiplayer model and the Forge model – a Monitor. Players can play actual games in Forge, goof around, kill each other, play Slayer where each team designates a Monitor to supply weapons, vehicles, equipment and cover on the fly.

Throughout the time you're editing you can press up on the D-Pad and change to your multiplayer model and play.

Once you're done with the editing you can start a party over System Link or Xbox Live and see how it works. You can build crate towers, grab a vehicle underneath a teammate, or have a friend jump on a crate and move it throughout the map.

All items spawned on forge will have a price, with weapons, crates and smaller items being cheaper than vehicles. There is a spending limit to the map which restricts total items than can be spawned.

As revealed in Bungie's 8/27/07 Podcast, you can add items in Forge that aren't available in a regular match. One example is the Yellow Powerup, the alternative to the Red Powerup (Overshield) or the Blue Powerup (Active Camoflage). The Yellow Powerup is completly customizabble in its effects; it can cause the interacting player to run faster, jump higher, grow an overshield/active camoflage, and even change the player's colour. Effects aren't limited to one or two at a time, but rather a number of effects can occur simultaniously. The hosts described it as equivalent to an "instant juggernaut."

Trivia
Another example is the telaporter of doom. You throw the receiver into the death zone(outside the ring of auto turrets) on Snowbound or Sandtrap and then levitate the transporter through one of you unsuspecting enemies, he suddenly goes out and is killed.
 * It has been stated that the Elephant will not be among the objects that can be spawned due to its size and specific purpose on maps.
 * Forge will keep track of stats and kills. It has been confirmed by Bungie that you can save your creations. Also, if your creation is liked by Bungie, they will put it up to be downloaded by other players for use.
 * You will be able to create teleporters with more than one destination portal; providing the ability to create such interesting features as a "Schroedinger's Teleporter" - where an "IN" portal could send you to either a power-weapon spawn or a bottomless pit.

Fun Physics
Place a grav lift in Forge, then place a turrets on a large box. Place the box on the grav lift Place a lot of grav lifts on sandtrap and drive your elephant over the top,shooting at it while it flies through the air, or try to fling it at something or someone. Using grav lifts placed on slightly slanted hills, launch fusion cores at enemies, trying to hit them and make them explode.
