D-9341 from SCP Containment Breach
D-9341, eventually identified as Benjamin Oliver Walker, is the main protagonist of the horror video game SCP: Containment Breach. D-9341 is currently classified as disposable personnel at the SCP Foundation. When entities like SCP 1471-A, SCP-049, and SCP-035 begin breaking out of the Foundation’s containment protocols, D-9341 must do everything he can to survive the horrors housed within and make it out alive. D-9341 wears a standard orange-colored inmate uniform with the SCP Foundation’s insignia on the left breast and has access to a clipboard with information on some of the Foundation’s housed monsters.
SCP-035 from SCP Containment Protocol
SCP-035 is an extremely dangerous object and part of the SCP Foundation’s collection in SCP: Containment Protocol. Also known as Possessive Mask, SCP-035 escapes containment along with countless other dangerous entities like SCP-1471-A and SCP-049. SCP-035 can possess anyone who wears it, which will result in their bodies decaying at an extremely fast rate. The Possessive Mask is one of the many horrors D-9341 encounters during the course of the game. To recreate the look of SCP-035, use black acrylic paint on a white comedy mask to create the long, black tear tracks that ooze from it, as well as to dirty a white shirt. Black body paint can add an additional detail by using it on your hands and arms.
SCP 1471-A from SCP Containment Breach
SCP 1471 is a mysterious app that, once downloaded, eventually leads to the user seeing SCP 1471-A, a humanoid wolf creature with a skull for a face and creepy, milk-white eyes. While SCP 1471-A’s true intentions are not fully understood, it is generally considered best to avoid it in the game SCP: Containment Breach. To create an SCP 1471-A costume, you will need an animal skull mask, tattered wolf ears attached to a messy black wig, and wolf-like hands and feet. While the game version shows SCP 1471-A dressed in black shirt and pants, there are many interpretations of its clothing, though its costume almost always includes rope tied around the waist like a belt.
SCP-049 from SCP – Containment Breach
SCP-049 is one of the terrifying creatures catalogued by the SCP Foundation. The SCP Foundation started as a form of online collaborative storytelling and has since morphed into a video game franchise among other things. SCP-049 appears in the game SCP – Containment Breach. It is humanoid and appears dressed as a surgeon from the European medieval era. Unfortunately this is not a doctor that heals. Any human it touches becomes a reanimated corpse that is bound to do the will of SCP-049.
Although SCP-049 is itself largely unknowable – since getting too close can turn you into an undead puppet – dressing up as SCP-049 is relatively easy. All you need is a black hooded cloak or robe, a grey plague doctor mask, black boots, and black gloves. It helps if you make the sleeves of the robe a bit tattered and if you wear black clothing underneath so it seems as if there is nothing under the robe but darkness and void.
