Murder
Golly! it looks like you're trying to find out more about SS13's oldest past time! Suffice to say, you shouldn't really be looking at this or using any of these methods unless you're an antagonist!
Murder most FOUL
It's fair to say that as a traitor/wizard/changeling/badguy you're going to have to kill a few people. You might even have an objective to kill someone! There are many ways to commit the foul act, and the choice is yours.
Murderous Methods
There's more than one way to skin a cat, and there's FAR more than one way to kill a man, especially in SS13. Below are some of the basic ways, feel free to mix, match, and create your own ways to butcher your fellow man.
Fists
A good, old-fashioned beating is a half decent way to take down an unarmoured opponent. Set your intent to harm, aim for the head, and whack away. Actually punching someone to death takes a long time, but a punch to the face can stun your opponent long enough to allow you to use another method of finishing them off, such as strangulation or spacing. Punches to the face have a good chance of knocking someone out or down, giving you plenty of time to finish them off. Punches to the stomach have a decent chance of winding your opponent, which doesn't last long but gives you a little time to work with. Your fists are only good weapons against opponents who are not wearing headgear. An opponent with any sort of headgear is highly resistant to the stunning effects of your punches - even the knitted stocking caps in clothing lockers provide occasional protection from a fist. Best look for a weapon before taking on someone with gear.
Blunt Objects
Ah, a good old fashioned toolboxing it is! Incapacitating someone with a blunt object can be easy enough, killing them with one can be a bit more tricky, however.
You will generally want to knock your target unconscious first, unless you enjoy jimmy mcvictim running round the station bleating about what a bad person you are as you chase after him and try to beat him senseless. If your target is incapacitated, it's a good idea to drag him off somewhere secluded while you finish the job. Beating someone to death takes a fairly long time, even using something hefty. Aim for the head, and use a fire extinguisher, metal bars, or an oxygen tank - something with some good weight behind it!
- some traitor weapons, such as the artistic toolbox, Cyalume sabre and Butchers knife are able to kill people very quickly!
Strangulation
If you manage to get a stranglehold on someone, you can double click the grab icon to start squeezing the life out of them. Being strangled keeps them unconscious as long as you maintain your grip, so they've got absolutely no way of fighting back. You're guaranteed to kill them as long as you don't stop strangling. Unfortunately, strangulation is one of the slowest ways to directly kill someone, and as soon as you drop them, they will start healing the oxygen deprivation damage.
As with other methods, the main difficulty lies in getting the necessary stranglehold on someone in the first place. Since you need to grab them three times and moving away from you will let them break free, you'll need to stun them or knock them unconscious before you get to work. Any helmets or headgear they're wearing will need to be removed beforehand as well. As such, strangulation is more a finishing move on someone who's already stunned than an actual way to win a fight.
Spacing
It's very difficult to space an enemy who is up and fighting, but trivial to space someone who's stunned. Drag them to the nearest airlock, open it, grab them, and throw them out. The combination of oxygen deprivation and cold damage (you did take their internals off, right?) will kill a person very quickly indeed. Even if they have a radio, they won't be able to yell for help since there is no air!
If your target is wearing a spacesuit, take it off them, then space them. Spacing is a surefire way to kill someone and only on very rare occasions will their body ever be found. In fact, even if you've already killed your enemy, it's a good idea to space their corpse to ensure they never come back, since even if their body is found most of the time the person will just loot it and move on. Dragging it all the way back to the station for revival is a chore, after all.
Gibbing
Much like spacing, gibbing a person is very difficult unless you've incapaticated them first. there are two ways to gib an enemy, the 'Gibber' located in the chefs kitchen, and the 'crusher' located at disposals next to eva, or accessed by a disposal chute. Both these methods will require your target to be immobilized before hand, and the inherent danger of fighting so close to the crusher can have.. unfortunate results.
To use the chefs gibber, grab your unfortunate victim and click on it. once they are forced inside (there is a delay) you can click the gibber twice to turn them into a pile of meat and gore. A gibbed target can NEVER be revived!
Guns
Lethal guns aren't very common in SS13. Security Officers have non-lethal tasers that are great for stunning people for easy murdering, but actually lethal guns are typically only used by the Captain and, on occasion, Head of Security.
There are also Laser Guns, which can be ordered by Quartermasters and unlocked by id's with security access. They aren't great but emptying their battery into someone will knock them into critical condition, allowing you to finish them off easily.
The Detective's Revolver does absolutely terrible damage and is not worth mentioning.
The Syndicate Revolver, while loud and obvious is very also powerful, and can drop a person into critical in 2-3 shots, provided they are not wearing armour. The revolver comes with only 7 shots to start with. Don't try to beat anyone with it, if you run out of ammo, the damage is laughable
The Amplified Vuvuzela is an Assistant-only traitor item, and rarely sees any action and is mainly used for the stunning effect rather than the mediocre damage it deals. The best lethal weapon on the station is the Energy Gun. The Captain starts with one and the HoS has access to 3 of them. They can be toggled between lethal and stunning. It's extremely easy to kill someone by stunning them and then following it up with a few lasers while they can't fight back. Plus the Egun holds 8 shots, giving it the largest battery/clip of any ranged weapon.
The Derringer does a piffling 20 damage and stuns just long enough for you to strip/strangle someone. Really a weapon of surprise or last resort, it is far more useful to escape from say the brig, or an opponent who has taken away your other weapons.
The radiation crossbow, while technically not a gun, serves the same purpose. Despite being called a 'stealthy weapon' it makes a large twang noise and fires a highly visible green bolt. huh. Anyone hit by the bolt will take heavy toxin and radiation damage over time, collapsing occasionally until they die. It fires a single shot, which recharges over time. Underestimated.
Bombs
When it comes to bombing, the bigger the better. A custom made bomb from Research will gib anyone within a decent area of the explosion, and likely kill anyone in a very large area since they'll be exposed to space and will suffocate. Making one of those is a time consuming process, though, and the other bombs you can get are underwhelming. The Syndicate Pipebomb is overpriced and not hugely powerful. The Research Director's bomb is decent if you really need one, but pretty small. And regular pipebombs only destroy one square, and typically aren't worth the effort of building.
Tips!
Get creative. There are ways to kill someone not listed here. Teleport someone into the Toxins mixing chamber. Throw someone into the singularity. Set them on fire. Poison them.
