===[[File:Changeling.gif]] Changelings===
[[Changeling|Changelings]] are alien entities that have infiltrated the station. They can easily change their appearance at a moment's notice. If there are confirmed sightings of Changelings, be wary. Sometimes you will encounter one with bio-organic armour, a shield that stops ranged disablers in their tracks, and an incredibly deadly arm blade. Don't underestimate them under any circumstances!
Due to their abilities, it is possible for a Changeling to kill a fellow Sec Officer and impersonate him. However, you should note that they will lack a [[Security_items#Mindshield_Implant|Mindshield Implant]] unless they had themselves implanted. Be wary of Sec Officers without Implants, as they should be arrested or kept under close watch. While you are free to terminate a confirmed Changeling, you must be 100% certain that the suspect is a Changeling before executing. If you cannot prove they are a Changeling, ask the Warden/HoS to give them a Chem/Tracking implant to watch their future activities. So if Joe Innocent walks out of the brig with a Chem Implant displaying a red or blue dot above their head on the SecHUD, and later on you see Alex Antag with the same dot, you will know that they are probably Changeling.

The same standard tactics in subduing a Traitor apply to subduing a Changeling, however, do be wary that some Changelings can get up instantly after being stunned and sometimes melt their handcuffs. If they do, you may need to switch to lethal.
