Enforcement of these rules is at the discretion of admins.
Admins are fully accountable for any consequences should they invoke this rule. Admins are also allowed to intervene in rounds when it is in the best interest of the playerbase.
Don't be a dick.
We're all here to have a good time, supposedly. Going out of your way to seriously negatively impact or end the round for someone with little IC justification is against the rules, this also includes harassing a player OOC (Out of character). Legitimate conflicts where people get upset do happen however, as detailed in the escalation section of the rules.
Do not use information gained outside of in character means.
I.e.. metagaming. This especially refers to communication between players outside of the game via things like Skype, known as metacomms. Characters are otherwise allowed to know everything about ingame mechanics or antagonists, as well as keep persistent friendships or relationships with other characters when not for the purpose of unfair advantage by teaming up together for little IC reason.
Do not say in character (IC) things in the out of character (OOC) chat channel.
Do not say OOC things in IC either. There is an exception for OOC in IC where terms like 'clickdrag X to Y, or look for the tab' is used to help a player.
Lone antagonists can do whatever they want.
Short of metagaming/comms, bug/exploit abuse, erotic/creepy stuff, OOC in IC or IC in OOC, and spawn-camping arrivals. Team antagonists can do whatever they want as per lone antagonists, as long as it doesn't harm their team. Non-antagonists can do whatever they want to antagonists as per lone antagonists, but non-antagonists are not allowed to pre-emptively search for, hinder or otherwise seek conflict with antagonists without reasonable prior cause. Non-antags acting like an antag can be treated as an antag.
Players in a head of staff, AI/Silicon role, or a team conversion role require a minimum amount of effort; generally considered to be not logging out at or near roundstart.
Notify admins if you cannot play these roles and must leave near round start and make an attempt to inform other players IC as well for head of staff or AI roles. Abuse of a job position, particularly Rule 1 breaking abuse, is not allowed.
In-game administration rulings are final.
Incidences of admin abuse, negligence or disputed rulings can be taken to the forums. If an admin says something was 'looked into, handled, resolved' etc, regarding an issue, it is unlikely an admin will provide any further information. Admins are under no obligation to reveal IC information. Deliberately lying or misrepresenting facts in adminhelps will be dealt with harshly.
If you regularly come close to breaking the rules without actually breaking them, it will be treated as the rules being broken.
Repeated instances of the same rules being broken may be met with harsher consequences. Baiting people into situations where you can report them to admins will be dealt with harshly.
Erotic/creepy stuff is not allowed.
No form of erotic roleplay is allowed on the servers, including things that could be construed as sexual by unwilling participants.
Players need to be the age of 18 or above.
This rule is for the benefit of and is meant to protect people who shouldn't be playing here due to the nature of the SS13 community. Your age won't be hunted down, but if you admit it to us in admin PMs, or other places within the /tg/Station13 community (the official Discord server, forums, OOC chat, etc.), you're getting banned.
Losing is part of the game.
Your character will frequently die, sometimes without even a possibility of avoiding it. Events will often be out of your control. No matter how good or prepared you are, sometimes you just lose.
Escalation and roleplay.
Going out of your way to seriously negatively impact or end the round for someone with little to no justification is against the rules. Legitimate conflicts where people get upset do happen; however, these conflicts should escalate properly, and retribution must be proportionate. For example, this means you shouldn't immediately escalate to murder when someone refuses to leave a certain area or give back something they stole.
Self-defense is allowed to the extent of saving your own life.
Putting someone into critical condition is considered self-defense only if they attempted to severely harm or kill you. Preemptively disabling someone, responding with disproportionate force, or hitting someone while they are already downed is not self-defense. Fistfights and the like are acceptable, assuming that both players have a reasonable justification as to why the fight started. Assault without any warning is almost always unacceptable in most circumstances.
Chain of command and security are important.
The head of your department is your boss and they can fire you; security officers can arrest you for stealing or breaking into places. The preference would be that unless they're doing something unreasonable, such as spacing you for spraying graffiti on the walls, you shouldn't freak out over being punished for doing something that would get you fired or arrested in real life. This also means that if you're in the chain of command, and especially if you're in Security, you're expected to put in some effort and do your job.
Validhunting and security.
If you are not part of the security team (HoS, Sec officer, Warden, or Detective, sorry lawyers) you should not go out of your way to hunt for potential antagonists. You can defend yourself and others from violent antagonists, but you should not act like a vigilante if a security force is present. The exception to this rule is when game modes such as blob or nuke ops appear on the server - you are free to fully engage with these antagonists, after all, they're a pretty massive threat to everyone onboard.
Antagonism, murderboning, and roleplaying as an antagonist.
You're an antag, great! Try your best to play the role to drive the round forward, inserting conflict into the round is important. Your actions should make the game more fun, more exciting and more enjoyable for everyone (Though some people will just lose, and that's part of the game.). You can treat your objectives as suggestions on what you should attempt to achieve but you are also encouraged to ignore them if you have got a better idea. Certain antagonists are restricted to the kind of death and chaos they can bring to the round, while others are not; refer to the murderboning chart for specifics. You do not have to act in a nefarious or evil way, but you should make an effort to add to the round in some capacity.
Deal with the bad guys in proportion to their crime(s)
When dealing with antagonists deal with them proportionally to their crime(s). Someone who stole the captain's medal shouldn't be immediately lasered to death, but lethal injecting someone who has killed four people is understandable. If an antagonist shows a willingness to engage with you, do your best to reciprocate it, though leniency as to their punishment is still in your court.
Do not spam in either OOC channels or IC channels.
This applies to both typical spam and reading porn or copypastas (like WGW). In the latter case, even one instance of reading it once in-game is against the rules.
Don't use OOC information or knowledge that your character would not reasonably be aware of just to give yourself an advantage.
Do not powergame. Powergaming is gearing up or preparing in other ways to face an issue that is not related to your job and is not currently a credible threat. Someone going missing on the station, and then you making a stunprod to wield whenever you go into maint is powergaming. However; knowing there have been murders occurring across the station, and grabbing a stunprod while you go to fix wires in maint is fine.
Play as a coherent, believable character.
Real life realism is not required, and you are encouraged to be a little silly within the context of the SS13 game world. (Clowning around, people spontaneously exploding and creating ridiculously elaborate machinery are all non-serious things but yet a vital part of the game world.) There's a good chance your character still wants to have a job at the end of the day, so you should probably act like it.
Stay in your lane.
Stay in your lane. This mean that you should do the job you signed up for and not try and do other people's jobs for them. If you need something from another player you should attempt to ask them to get it for you instead of just taking it. If there is no one around to do a job or you get permission to help or grab something it is acceptable to stray from your lane.
The not-so-secret rule of sticky situations and mayhem.
Please be considerate of other players, as their experiences are just as important as your own. If you aren't an antagonist and yet you really want to play out a hostage situation, or turn someone into a living cake-cat abomination, or just dick around a little, confirm with the involved and affected players ICly first. If everyone agrees to being subjected to whatever terrible atrocities you have in store, then you're good to go. Please keep in mind that this rule does not protect you from IC consequences, such as getting arrested by security. If you are going to RP as a rude dude, given that your victims have given you the okay, you still have to own the responsibility that comes with your decision. This means, no, you can't kill a security officer because they tried to arrest you for murdering the clown, even if the clown agreed to being murdered.
