"When the original Forge mode was released back in 2007, who could have known the impact it would have on Halo? More than just a map editor, Forge allowed players to collaborate with one another and create brand-new, unique experiences in a multiplayer session. For the first time, friends could test a map live while it was being built. This empowered creativity, allowed for rapid iteration and led to the discovery of all sorts of happy accidents. Best of all, building in Forge could be as fun as playing the game. Halo players embraced this new tool, letting their imaginations run wild. Since then, some of the most fun and creative ideas in Halo have come directly from the community, via Forge."
