What can I say. It's either a blessing and curse.
TL;DR: IPCs are nerds. Play nerds. Be nerds. Fight less, Work more. EMP is universal hates, don't worry. Laugh at everyone when catbeast or brainrot virus broke out. Oil leak isn't bad but you are fucked if no welders and people forget about it or Roboticist are dicks.
Do remember that playing as IPC, you chose to play as the race character that has unique style. You sacrificed the play style of being the organic and become fragile skeletal machine people with TV head.
And indeed as said, IPCs are fragile. But Physically. A few hits and their limbs wold pop off or having their TV head flung away from one simple high-five slap in the head. And being in void space without any space suit will also damage them as much as organic do.
The only and obvious problem with the IPCs is that they are, like androids, sustainable to EMP and ION greatly. But you should know that EMP is never a good thing to almost all the races or players at all. Vox can die from EMP due if their sack for example. And a lot of players do like to set up their spessman to have Cybernetic limbs. Or at worse case but hardcore and awesomeness: Cybernetic heart. EMP blasts also mess up a lot of any electronics near by let it be the vendor, camera or the airlocks especially the fire airlock and will crush the unfortunate player that come upon during the EMP. Security Officers will complaint about their laser weaponry being instantly drained and have to run back to Brig for recharge and restock, the victims will feel bad to realise their headsets are disabled and not being able to call for help or even certain antagonists will have issue on using the EMP but not unless they are completely cybernetic-free but they will still have to deal with disabled airlocks and others.
Now lets talk about good news being IPCs. You are very suitable for Engineering and Medical tasks (while completely useless on Virology and Genetics) due of you being immune to most of unseen hazards that the organics fear let it be suffocation, radiation, virus outbreak or harmful atmospheric. You can even walk free into plasma leak as long no one dare light and ignite up. Unlike how Vox suffocate and grow dust in their lungs if they breath Oxygen while others oganics are vice versa, Plasmamen won't go far with their suit off and plasma out. And surprisingly, water won't do anything to you, EXTERNALLY, unlike Greys. Just don't drink water.
Another thing to note is that IPCs are also immune to pain which will come in handy in certain situations. About all the races will slow down the more pain they gain and eventually succumb to it. Meanwhile, IPC will be still be able to run with many dents and burn they endured AS LONG both of their legs are still attached. So consider to avoid any unnecessary combat.
You know organics will eventually complaint if there's no Chef on the station or that he refuse to cool anything good and are forced to live up with snacks and hot chocolate cup. Organics will go famished and have movement speed penalty if not well fed (or getting Weight Even virus from Virology). While in the same time. IPCs feed on the Station power via APCs. And there are many APCs in every corners. And engine power would never ran out as it's the top priorities of all.
Now speaking of the recent "nerf". I think it's kinda important to have but also need to be heavily adjust from its current state. Oil leaks as bleeding to IPCs is quite interesting and help out the situation of being in eternal Crit. Back then IPC can just still be alive but remains in Crit forever and not being able to talk, stand or die out unless ghosted. However. I did encounter an issue where I could not fix up one of the IPC's leaking (after fixing much more awful damages they got into by playing with EXPERIMENTOR) no matter what I do. I tried to weld their every parts only to get message "Nothing to fix!" while examining them clearly says that they are still leaking to the point that I had to put their robot brain into new IPC body from Roboticist Lab as the only way to fix them. And while Oil Leak can be common damage IPCs will encounter and welding themselves to fix it up can be easy enough. Having enough Roboticists to help you out with the oil is not. As the only way to get more oil is to go to Roboticist and ask them to offer their oil canister to you to drink or the issue is that only the Roboticist have only two canister cans and one Tank to refill. If their Lab exploded from that silly syndicate payload bomb, you are fucked. While Organics relay on large Medbay, the Medical Staffs, pills/patches and being able to regenerate blood by consuming food, get IV dips or iron pill and many others benefits from Virology and Geneticist or implants, IPCs must relay on only two limited Roboticist or breaking into the Lab and hopefully they can get what they needed to fix themselves or at worst case is to meet real pain ass Roboticist players that will completely ignoring you for their Phazon project whole shift. And the way they have to "drink" oil canister for me seems a bit ridiculous logically. As I expect it to worked like IV dip or at least some sort of injection on my first time using and drinking it.
But yeah... While I don't mind Oil Leak. I say the way IPCs Oil works, how to fix it, how to refill it and where else to get it could be adjusted a bit comfortably.
