343 Industries conducted a panel at PAX EAST on Friday where it revealed a brand new Forge map for Halo 4. Better yet, this map will be made free to all Xbox 360 owners not long after the Castle Map Pack is released.
The new map is called "Forge Island" and will be made available to download for free on April 11. The map consists of three separate flat islands - large, medium and small - with grass fields surrounded by Forerunner structures. According to panel attendees Daniel Duncan and Tomasz Macieik, the map features some UNSC pieces and also new designs.
The entire map is very large in size but is reminiscent of the existing Forge map, Ravine. 343 Industries demonstrated a remake of Halo: Combat Evolved's "Hang 'em High" map built on Forge Island.
When asked if there are any plans to do any updates to Forge with a future title update such as adding precision editing, 343 Industries responded that there are no plans for that now. Any changes or improvements to Forge will likely come with Halo 5.
