Details on Halo 4′s Forge Mode
Halo 4‘s editing mode, “Forge,” is being developed by Certain Affinity, a team that has worked on a couple of Halo map packs in the past.
Certain Affinity has revealed some of the system’s new features, which include the ability to lock down objects, duplicate items, magnetize objects to connect them to each other, and a new lighting system. A new system called “Player Trait Zones” will change parameters when players enter, which can, for instance, slow players down or let them jump higher, and a new object called “Grav Volume” can alter or reverse gravity.
Halo 4 is set to release in November for Xbox 360.
