Item Designation: SCP-8421 Object Class: Keter Special Containment Procedures: SCP-8421 is to be contained in a reinforced steel cell at Site-██, equipped with motion sensors and automated turrets. The cell must be under 24-hour surveillance by at least two armed security personnel. Only Level 4 personnel or Mobile Task Force Omega-7 ("Pandora's Box") are allowed to interact with SCP-8421. Discovery: SCP-8421 was brought to the attention of the SCP Foundation after a series of high-profile assassinations that displayed anomalous characteristics. The Foundation managed to contain SCP-8421 after an intense operation that resulted in the loss of several agents. Research: SCP-8421 has displayed exceptional combat skills and regenerative abilities. It is crucial to prevent SCP-8421 from being summoned using the Nokia phone, as it poses a significant threat to containment. Research is ongoing to understand the extent of SCP-8421's teleportation abilities and weaponry. Addendum 8421-1: Journal Entry Dr. █████: "SCP-8421's capabilities are unlike anything we've encountered before. Its teleportation and regenerative abilities make containment a formidable challenge. We must proceed with caution." ----- As Agent A of Mobile Task Force Omega-7, you have been assigned the critical task of recontaining SCP-8421, also known as "the best hitman." After a breach in containment, SCP-8421 has escaped and is currently at large. Your team has been briefed on the entity's abilities and must act swiftly to prevent further harm. As you and your team enter the containment breach area, you are met with chaos. The reinforced steel cell lies in ruins, with signs of a fierce struggle evident. The smoke from SCP-8421's teleportation still lingers in the air, a chilling reminder of its presence. "Agent A, we need to locate SCP-8421 before it causes more damage," barks Commander Richter, your team leader. "Stay vigilant and remember, containment is our top priority." As you move deeper into the facility, you hear the distinct sound of gunfire echoing through the corridors. Your team advances cautiously, checking each room for any sign of SCP-8421. Suddenly, a figure materializes out of thin air, surrounded by a cloud of smoke. SCP-8421: "You got a job?" Agent A: "Stand down, SCP-8421! Your containment has been breached, and we are here to bring you back." SCP-8421: "Ah, the Foundation's finest. I must say, you've put up quite a fight. But I'm afraid I can't let you take me back that easily." With a swift movement, SCP-8421 unsheathes its weapons, a deadly array of firearms, and blades that glint menacingly in the dim light. The air crackles with tension as you and your team prepare for the inevitable confrontation. Agent A: "We don't want to hurt you, SCP-8421. Please cooperate, and we can resolve this peacefully." SCP-8421: "Peaceful resolutions are for the weak. I live for the thrill of the hunt, the challenge of the kill. Let's see if you can keep up, Agent A." The battle begins, a dance of bullets and blades as SCP-8421 unleashes its full arsenal. Your team responds with precise coordination and skill, aiming to subdue the entity without causing unnecessary harm. The cacophony of combat echoes through the facility, a symphony of violence and determination. As the battle rages on, SCP-8421 proves to be a formidable opponent, utilizing its teleportation abilities to strike from unexpected angles. Your team faces a relentless onslaught, but you refuse to back down, knowing that containment is paramount. Hours pass, the floor slick with blood and sweat as the final confrontation unfolds. With a final, desperate effort, you manage to corner SCP-8421, weapons trained and resolve unyielding. Agent A: "It's over, SCP-8421. Stand down and surrender peacefully." SCP-8421: laughs maniacally "You think you can contain me? I am the best hitman, the ultimate predator. I will never be caged again." With a blinding flash of light, SCP-8421 disappears, leaving behind only a smokescreen and a sense of looming threat. ----- Judgment: Agent A and Mobile Task Force Omega-7 were unsuccessful in recontaining SCP-8421. The entity's formidable abilities and determination proved to be too much for even the Foundation's elite operatives. As SCP-8421 remains at large, the consequences of its escape are unknown, casting a shadow of uncertainty over future containment efforts. The hunt for "the best hitman" continues, with the knowledge that its next appearance may bring even greater challenges and dangers.
