This paper model is a C-10 Rifle Mk. VI, a variant of the C-10, which is a terran canister rifle issued to ghosts, from the military sci-fi real-time strategy game StarCraft II, the papercraft is created by [unknown]. The size of finished model is about 232 (H) x 56 (W) x 863 (D) mm.
The C-10 Mark VI entered service in the Terran Confederacy shortly before the Fall of Tarsonis. It was first used by Horvald Winston to kill a Kel-Morian mining baron, James Fortune. It entered the arsenal of the Terran Dominion, which has been unable to improve the design. It is constructed out of neosteel and polymer.
Although the Mk. VI is unwieldy in the hands of others, ghosts are able to use it as both an automatic weapon and as an anti-personnel sniper rifle, capable of a one-shot kill.
The weapon fires 25mm antipersonnel rounds. These rounds appear to be charged with energy instead of relying purely on conventional explosives and have the power to destroy siege tanks from the inside. The Mk. VI is also equipped with a flashlight, can fire EMP rounds that punch through shields and deplete energy sources, lockdown rounds, and has retained the low frequency targeting laser that is used to guide tactical nuclear missiles and now drop pods to their intended destination. The accuracy of ghosts has improved thanks to the Mk. VI containing a magnetic grid tracker to verify coordinates.
