Reckless Ri1ey walks us through all the new Forge pieces available in Halo 2: Anniversary from The Master Chief Collection in this video. Quite an impressive palette. Keep in mind, forgers, that the map override bug is back, so maps are not saving correctly in Halo MCC and you will want to save multiple copies of your maps, all with different names, as you create them, or face losing your hard work. Unfortunately, we only have 50 slots to save content in, so this will fill up fast for creators. You can discuss this issue in the Waypoint support forums here.
Halo 2 Anniversary: All New Forge Blocks and Terrain!
