ack your way through the network, infiltrate nodes, and use them to locate your target. You start with a single node. Drag a node onto another node to execute the Hack Program! The hack program will infiltrate the targeted node, with tougher hacks taking longer, based on the attacking and defending nodes' respective power. Drag a node to the edge of the screen to turn it into a Watchtower Program, to expose nearby nodes. Higher-powered nodes will allow you to see further. Nodes that are running a program will turn yellow. Right-click on a yellow node to terminate it's program.
