Forge

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

Background
Forge allows players to customize maps for custom game (online or offline) use. Options include 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 having money to allow you to not use an excessive amount of memory. By deleting existing things off of a given map, you can actually place more things. The spending limit is merely a counter to help the player gauge how much they can place on the map at a given time, no real currency is used.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. While in Forge mode, the player can press up on the D-Pad to cycle through Monitor or Player modes. Note this feature can be changed so only the party leader is able to become a Monitor and edit the map.Once you're done with the editing you can start a party over System Link or Xbox Live and play test it for flaws.

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 Over shield or the Active Camouflage.The Yellow Power up is completely customizable in its effects; it can cause the interacting player to run faster, jump higher, grow an overshield/active camouflage, and even change the player's color. Effects aren't limited to one or two at a time, but rather a number of effects can occur simultaneously. The hosts described it as equivalent to an "instant juggernaut." You can only change the actual properties of this custom power up via game settings.

While playing as a monitor a health bar is shown at the top and its basically the same amount as a Spartan's. This can be tweaked as well to allow the Monitor to have damage resistance, overshields or be invulnerable.

Cool Things to Try

 * Warthog Launch - (See picture) [[Image:447190-Full.jpg|right|thumb|170px|Piled like this, a hog can be launched across Sandtrap.]]


 * Elephant Flipping - Use all possible explosives on 1 side of an elephant and blow them up. Alternatively, you can simply push a Scorpion tank into the Elephant and lift it up...


 * Magic Carpet Ride - Spawn a crate, and have another player ride on top as you move it around


 * Explosion Mania - Create a never ending explosion of fusion coils all over the map, then try to play the map against friends and see how long you can survive


 * Monitor of Death - Be the monitor and deploy a tank, then throw it around the level and try to splatter the other players


 * Grenade Hold - While not in monitor mode throw a grenade, but right after pressing the left trigger press up on the d-pad to go into monitor mode. If done correctly the grenade shouldn't have been thrown. Then when you see an opponent, go back into normal mode and the grenade will be released and thrown. It works really well with plasma grenades but any kind works.


 * Floating Objects - There are two ways to do this, first, set an object down onto an object a friend is holding (your friend's object must be as big or bigger or it will be pushed through) and, once set down, have your friend sell the item they are selling, your item will remain in the air as though your friend's object was still holding it up. Another way to do this is to have a friend shoot your object as you let go, it will remain in the air. Unfortunately these objects only stay in the air until moved. Fortunately some objects (such as teleporters) are unmovable, and can be used as floating platforms for other items, this allows for flying bases, although they are not always stable without multiple teleporters under them.


 * Flying Vehicles - Normally if a player is driving a vehicle and a monitor picks it up the player is removed, but if the player is in the sideseat of the vehicle they will stay in it, able to shoot and move as usual as the vehicle is moved around the map. This can also be done with machine gun turrets.


 * Unreachable Items - It is easy to place items in places where players cannot normally reach, this makes taunt power weapons, powerups, equipment and vehicles an easy and fun thing to place.


 * Flying Elephant - By setting up large numbers of fusion cores and other explosives to spawn inside of elephants, it is possible to have them fly into the air, dropping explosives at random as they travel high above the map.


 * Obstacle Course - If you have good (co-operative) friends, it's fun to make obstacle courses, simply construct a path that requires teamwork to travel through (ie: steps that require stacking to get on top of, objects that need to be in one place and need to be moved to another along a narrow path, a wall of objects that needs the force of multiple players to move, etc.) and make the start a bomb spawn point and the end a bomb plant pad, this can easily be turned into a two team race.


 * Obstruct the Windmill on Last Resort - This can be done by simply flooding the trench with large items, although it is impossible to stop the mill, the result is entertaining more often than not. If you want to get a bunch of stuff into place at once, try spawning it next to the trench and then using grav lifts to move it into place.


 * Enviroment Battles - By making a gametype where player damage is 0% enviroment battles become strategic war games. Since players can still effect the enviroment (ie blow up fusion cores, light propane tanks, flip large objects etc.) the enviroment is a viable weapon.


 * Block Grav Lifts - Blocking grav lifts with large objects like crates is hillarious. Whether the map is used for king of the hill or slayer, the obstruction is either a dangerous waypoint or a noob trap.


 * Disable Door shields and turrets on Snowbound - Load the big underground entrance (the one near the shotgun) with all the explosives on the map (use a canvas version of the map preferably) then set instant respawn trip mines (with minimum runtime maxed out) near the pile, throw a bunch on and let it rip, it should disable the entire shield network and even shutoff the turrets


 * Under Snowbound - place a mongoose under one of the low rocky overhangs (as close as you can to the edge) in the underground portion near the shotgun spawn. Then place two large crates near it making it only possible to reach it from behind. Enter the mongoose and then exit, but be quick to go into monitor mode, if you are too slow you will die. A way to make this easier is to have 1 person use this trick and place a 2 way teleporter above ground, and 1 on a ledge under the map.


 * Trip Mine Launch - Make instant spawn trip mines near a vehicle (within tripmine throwing range) have a friend sit in the vehicle and not move. Plant as many trip mines as possible (when the game cant handle any more, the first ones you place will disappear in a small flash of blue light). After setting all the mines you can, blow them up, this is a cheap and quick way to launch something without a difficult to build explosives pile.


 * Race Track - create a race track on any map, set the waypoints sequentially and add interesting obstacles, some cool things to do include making a waypoint in midair and a gravlift jump leading to it, and making a run through a wall of explosives.


 * Target Practice - set up fusion cores above a man-cannon and have them fall at set intervals, works well on valhalla when the trainee stands in the middle of the map with a sniper.


 * Mid-air spawning - Stack crates, or spawn an especially tall object to reach the desired height, place any objects you want to spawn in mid-air on top of the pile, then delete the objects underneath. Works perfectly to create an artillery effect on D-day maps


 * Secret Rooms - Block off a section with a tall sturdy wall, add a teleporter inside and place another one in some difficult to reach place on the map. Normally these rooms contain power weapons or multiple power ups making it a valuable room to control.

It also helps to add a teleporter back there so that other players can get to it without any hassle.
 * Outside of Last Resort - In the main room of the power plant (the biggest one) fly up to the invisible barrier and force the monitor onto a ledge high above the power drainer spawn, once up there fly towards the turbine in the back of the base, once you cannot move anymore, lower yourself off the ledge and you should be behind the fence separating the main base from the turbine. USE BOOST THE ENTIRE TIME it makes the process alot easier.


 * Party Hog - It is possible to drive the transport warthog in the Pit by using forge. First set up a teleporter on the other side of the fence (if you set it on the ground it will dissapear, so set it on one of the support bars on the fence) and then move the transport warthog against the fence with a large object (barriers work well) and then blow it up. When it respawns it will be drivable. It is possible to get the warthog across the fence. Be careful while in player mode on the outside of the fence since standing on the ground here for 5 seconds will cause you to suicide, this does not include standing on top of objects like the warthog, although it does include being in a vehicle on the ground.

Trivia

 * You take the form of a monitor (like 343 Guilty Spark) while you are in Forge mode.
 * The Elephant can not be spawned due to its size and specific purpose on maps.
 * Forge keeps track of stats and kills.
 * Created map variants can be saved and shared with the community. 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.
 * The idea of the was taken from Marathon:Infinity, which also has a map editor named Forge.
 * In the monitor form you can become invincible or almost invincible and so kill players by spawning weapons and using your human form or using the object spawning and grappling to splatter players. A player can also change into the monitor form and be used as a mobile resupplying dock or super weapon, making forge an amusing combat game.
