This papercraft is a life size Stalker's Helmet, based on the free-to-play cooperative third-person shooter video game Warframe, the paper model is created by Sinner. The size of finished model is about 285 (H) x 361 (W) x 218 (D) mm.
The Stalker is an ominous, vengeful figure that infrequently appears during missions, armed with powerful weapons and abilities to hunt down the Tenno.
The Stalker wears Warframe armor and is able to use ability powers from various other Warframes, in addition to Dispel, which is his signature ability. His arsenal is similar to that of the Tenno, utilizing a primary, secondary, and melee weapon. The Stalker's signature weapons are the bow, Dread, the scythe, Hate, and the throwing knives, Despair.
If the Tenno in question has completed The Second Dream quest, they will be confronted with a stronger, Sentient-geared Stalker instead. [Source: wikia]
