Chief Medical Officer

As the Chief Medical Officer you're in charge of the health of the crew. Good luck.

What You Do
You control the entire medbay. Make sure all the Medical Doctors are doing their job, the station's crewmen have their suit sensors on, the geneticist makes backups of personnel and etc. If you're the only person on the medical team, then you'll have trouble doing your job. You know almost everything about medicine, so you can perform surgeries, create chemicals, make genetic backups, clone and everything else, but you are not a super-doctor. Your job is to make sure everybody else in Medbay can do and is doing their jobs, not to be out there on the field yourself. You can take over for someone if there's an emergency, but otherwise, you're an administrator, not a field medic.

Outbreaks
When diseases break out, this is your chance to shine. You have a biohazard suit inside of your office. Use it. Then consult the Virologist and Chemist. You have the authority to isolate and detain anyone experiencing symptoms.

Vaccinate the medical personnel and quarantine the infected. Administer the drugs, keep people alive. Your Medical Doctors should be helping with this, if they're not, shout them into line.

Hypospray
This is your medical tool, your lifeline. It comes filled with 30 units of The Doctor's Delight, basically upgraded Tricordrazine. It's a fast injector (dealing bursts of 5 units, with a fill limit of 30 units). Filling it with Choral Hydrate might be a good idea, but then you need to get rid of the chemicals inside before you can fill it with medicine, and the only way to get anything out is to inject it into somebody. It's considered very bad form to just go around injecting people however.

Other good candidates are Tricordrazine or Inaprovaline.

Traitoring
So, you're a traitor CMO? Don't fret. You have many possible tools to help with your objectives. Your hypospray will help a bit, try filling it with Choral Hydrate for sedation purposes. You have access to Chemistry, so you can sneak in there and make some space lube or similar. You can pretend to "heal" hurt targets brought in, and even disrupt some targets getting cloned. Bottom line here is to be a bad doctor. As a changeling CMO, you've got plenty of options. One of your major goals is to capture Genetics so you can absorb genomes quite easily. The spray bottle and hypospray can both be used to knock out victims, and you can lure many humans on the pretense on healing them. CMOlings are best played stealthily. Try not to get anyone too suspicious with you, and see if you can snag an Assistant's card early for maintenance access (or ask the HoP for it.)
