About Graft & Wire
Have you ever wanted to open a lab where organs are grown instead of plants, and custom cyberwares are assembled instead of devices?
In Graft & Wire you run an underground biomaster workshop in a grim cyberpunk world. Manually grow synthetic organs, turn them into cybernetic implants, install modules, connect wires, calibrate the results, trade, and fulfill black-market orders.
Grow organs
Add nutrients and watch how a stem cell reacts to your decisions. Different nutrients change the direction of growth, the organ’s traits, and its future value.
Organs available for growth:
- Eye
- Arm
- Leg
- Lungs
- Stomach
- Heart
Create cyberwares
An organ is only the beginning. Insert cyber-modules, connect nerves and wires, calibrate systems, and finish the job well enough to charge a proper price for it.
Trade
Your main contact is the mediator: he brings orders, buys finished organs, and sells the resources you need. His market changes constantly: today there is a rare module, tomorrow an urgent order, and the day after that a chance to risk it all for a big payout.
Sell what you do not need, buy resources, catch profitable offers, and decide when to save credits - and when to invest in quality.
Complete orders
Every client wants something different: a cheap organ in a hurry, a rare modification, or an expensive cybernetic implant. Choose which orders are worth your resources.
From the game's Steam page.
