Bionic augmentation slots.
Right now the PC can become a bionic god by installing everything. Even weird combinations like having an integrated toolkit, finger laser, flamethrowers and a fusion blaster installed at the same time. All of which are supposedly installed in or are replacing hands and arms.
By having bionic augmentation slots the player will be forced to make a tactical decision regarding what to install. And depending on whether or not bionics will become removable, he’ll have to stick with that decision for quite some time.
On a related note, this was talked about on IRC a while back: Mutation slots that conflict with bionics installed in a corresponding slot, causing severe pain until the bionic is removed or breaking the conflicting bionic entirely.
A downside to having bionics installed.
Also, currently any bionic is a straight upgrade from having no bionics. Other than the risk of a failed installation there’s really no downside to having something implanted.
I feel this needs to change, because there is no way you can convince me that replacing you hands with hand-shaped toolboxes will not impact manual dexterity.
Having an integrated toolkit installed would probably give a severe penalty to dexterity. The same goes for hydraulic muscles: They may be stronger, but they’ll never be as responsive as the real deal.
The metabolic interchange and EtOH burner bionics would probably be integrated with- or replacing part of the liver. It seems only logical that missing part of your liver makes you more susceptible to alcohol and other toxins.
An internal furnace due to it’s size would probably be installed in the gut, and to make room some intestine would need to be removed with the effect of gaining less nutrition from food.
Any CBM installed in or right under the skin would probably be bumpy and look hideous.
Etc. etc.
In the end, having bionics installed should present a clear advantage in one gameplay aspect, while at the same time limiting the PC’s functioning in another.
Because while a blood filter bionic can quickly clean a patient’s blood when active, it will severely hamper the body’s natural, passive filtration if a kidney had to be sacrificed for it to fit.
Grouped bionics.
Right now it feels all bionics are grouped together in a single gray blob labeled “bionics”. Cata is a very thematic game and it’s bionics could do with much more variety. By subdividing general “bionics” into several groups and filling those groups out, Cata’s world would feel much more alive (or at least “lived in”). I propose:
-Medical bionics
A group woefully absent from the world of Cata. Where are the artificial kidneys, cochlear implants, implanted pacemakers and defibrillators, artificial pancreas(-es?) and grafts with artificial skin? If the health system ever gets expanded to include organ damage this group could shine.
-Professional bionics
Integrated toolkits, hydraulic muscles, the implanted welding glasses and anything that could be designed for professional use.
Should very rarely be found in hardware stores and (once Cata is capable of it) be found in industry-themed districts and -cities.
-Black market bionics
Implanted shivs and things related to that.
A group fitting with the dystopian future of Cata, and in particular to bridge the gap between civilian and military bionics. When the government wouldn’t give military-grade bionics to the general public, clever people would set up shop and make their own.
I imagine drug dealing cyborgs would be outfitted with these.
-Military bionics
Rotary machine guns, cloaking systems, and everything offensive, defensive and clandestine.
Should be found attached to military cyborgs, in bunkers, dead convoys and related places.
-[SPOILERTASTIC] bionics
Teleporters and fusion blasters and whatnot.
Rewards from labs and bunkers.
Surgery.
Why is the PC able to crack open his own face to install a cranial flashlight? Or install multifocal lenses IN HIS OWN EYES? Or preform brain surgery on himself to install quantum memory banks?
Small things like the fingerpick or internal chronometer CBMs should definitely be possible to install by yourself, on yourself, but invasive things like quantum brain surgery or implanted night vision shouldn’t.
I think it should only be possible to install those in a (ghetto) operating suite by a skilled NPC (once they don’t suck).
Finding an NPC skilled enough and clearing a hospital for him to set up shop, or alternatively, finding enough money to pay a surgeon (once factions work properly) would emphasize the idea that becoming a cybernetic god is a late-game goal.
