You gain the knowledge on how to create all the tech from the world shown in the Deus Ex games, this includes an array of knowledge in cybernetics, robotics, nanotechnology, VR and AR, and incredible surgical technique to actually implement and equip people with them. None of the tech you make will cause any incompatibility with a host’s body and will instead cause an effect like Jensen’s, unless you purposely design them to cause host bodies to reject them.
