I just had about the best round of SS13 I've ever played as a pseudo griefer, on /tg/ station. I started the round as an engineer, and immediately got my tools, made some stungloves, and ambushed an officer by the chapel, stunning him, stripping him naked and stealing his ID/clothes, while handcuffing him to a chair in the dark. I used my newfound identity to claim a vast arsenal of weaponry from security, wearing his ID the entire time, and break into the armory via a side wall so no-one could see I didn't have a loyalty implant. I then staged an attack in two places at once, flooding the brig with N20 to divert security's attention while I broke into the HOP's office, stunned him, and took his ID to give myself a brand new, unique identity. I spent the rest of the round in godmode, with all access, weaponry, stungloves, the works. The entire time security is looking for me, and even set up blockades at the escape hallway to catch me if I try to slip through. I stunned, stripped, and humiliated the HoS, leaving him in the theater with a clown costume on, so this is understandable. I get through anyways by enlisting the help of the clown, and build him a mech to wreck havoc on the security officers. (There were bananas EVERYWHERE.) Just before the escape shuttle launches, I walk into the front part of the shuttle (The restricted part, where the heads and captain congregate.), whip off my mask, give a big ol' hello and a smile, and drop a chloral hydrate grenade, knocking them all out. They spent the remaining minute before the shuttle launched in schoolgirl costumes and handcuffed to their chairs. It was pretty sweet.
Once I did something like that, but it was a special admin event.
I was friends with the host, so he gave me cultist powers (/TG/station). I never intended to harm anyone, just research the wonders of Nar-Sie. The power went out, and the station was going to fuck. I was a geneticist, and there were bodies piling up. The equipment was down, so I could not clone anyone. I took the energy gun of a dead officer, and the ID of an engineer. I grabbed a toolbox, and all the station was my playground. I could have set off a singularity, blew up the escape wing, ANYTHING I wanted to. But I was content with experimenting with the monkeys. I shot off a few warning shots at some looters in Medbay, and scared them off. Security was alerted, and a detective and the HoS were called in. I welded the door shut, and killed the power to the doors from the APC. They tried prying the door open, to no success. They eventually started shooting at me, and with my grand skills I dodged all their shots. They were in yellow, and a few bystanders (The looters ready to continue business once I was gone) were red. They eventually gave up and let me have half time on the timer if I came out peacefully. I had nothing better to do, as the firefight killed my sacrifices, so why not? I came out, and walked with them to the brig. I spent the whole time whistling, and driving them mad because they could not figure it out. They eventually had the "OH SHIT" moment that they did not search me. They took my backpack and found the gun and the Arcane Tomb. They flashed the cell and locked me in a locker, planning what to do next. They both decided that they would open the locker and shoot me, so they dragged me to the gibbing room. They both had their guns out, ready to fire. They swung open the door and... I flashed them. The moronic bastards didn't know how to do their jobs, so I got my flash still. It burnt out on the detective (He had his thermals), so I had to shove over the HoS. I shoved them both over and took their ID's, and ran off naked. I grabbed a robotics suit, a utility belt, and a backpack. They searched the whole station looking for me, but without success. I grabbed the ID of a dead roboticist as well, and looted chemistry with my tools. I had a grenade of metal foam, one of explosives, and one of sulfuric acid. I grabbed a gas mask and casually walked to the escape wing.
The shuttle was called, and I walked around infront of their blockade for the whole ten minutes. The shuttle was about to leave, and the duo were walking to the shuttle as well. I threw my foam grenade in the doorway of the shuttle, and removed my mask. I laughed hysterically in their faces as they riddled my chest with holes. As I was going faint, I pulled the pin on the acid grenade. They had pulled out their batons at this point, and were electrocuting me to death. Their clothes were destroyed, and they were rolling on the floor in utter agony. I gave one last laugh before going critical and the shuttle leaving us all to die.
"Necro910 was the cultist!"
"Necro910 has survived!"
The whole crew was raging "BUT WE KILLED U! WTF IZ DIZ SIT I H8 U"
I laughed at them, "I was merely critical. Not dead, shitscurity."
I proceeded to point out the hundreds of mistakes they made, and they continued raging. I left, with a smile on my face and my book in the air.
