* Changelings can now speak through their decoy brain if placed in an MMI (#78342) ## About The Pull Request - If a changeling's decoy brain is placed in an MMI, they will now be prompted to speak through it. - They can speak through the decoy even if incapacitated or dead (or fake-dead). https://github.com/tgstation/tgstation/assets/51863163/804bd48a-c4b8-4feb-b021-019ea70e4b8e ## Why It's Good For The Game The oft-controversial ling MMI test has been brought up time and time again so I figure I throw my cards in for a solution. We want as few ways as possible for people to hard and fast discover whether someone is an antag, especially changling which is supposed to revel in paranoia. This soft-patches out a big way, the MMI test, in which you place a ling's brain in an MMI to determine if it's vestigial and therefore, a ling. Now the ling player can provide some benefit of the doubt by speaking through the brain as normal, appearing active while actually in their body still. ## Changelog 🆑 Melbert add: Changelings can now speak through their decoy brain if it is placed in an MMI, to maintain the illusion they are actually dead and have been debrained. /🆑 * Changelings can now speak through their decoy brain if placed in an MMI --------- Co-authored-by: MrMelbert <51863163+MrMelbert@users.noreply.github.com>
