This is my Halo Reach Forge World recreation of the Pillar of Autumn as seen in the Halo Reach campaign and now Halo Anniversary.
Not the largest of my creations but does have the most attention to detail using Reach in game screenshots as reference, I'd say it took roughly 20hrs to construct the exterior and the starting points for the the interior's bridge, hanger and engine room.
Also my original version on my file share just for show version- [link]
My fellow Deviant
and War Buddy (Human/Covenant war) helped with the interior, we then created an altered version with minor changes to the exterior but a much more complex interior to support the invasion game type and now available on my friends file share here- [link]
and its accompanying gametype- [link]
