The Internicine from Armored Core Last Raven built in Minecraft. Armored Core is a third person mecha shooter and is the longest running game series by FromSoftware before the Demon's Souls/Dark Souls series came along. Last Raven is the final game of the PS2 era. The Internicine is the final boss area of 6 of the 7 possible endings.
I started these builds in Tekkit 1.2.5 ~5 year ago before migrating them to Vanilla Minecraft after the beta. During those years I've been working on them periodically.
