Primary statistics are not used directly. They are a result of the drone chassis and any upgrades installed. They are:
Memory - Drone's memory storage capacity. Useful for caching combat data from sensors as well as storing the complex logic and data required to operate an autonomous AI.
Sensors - The sensor systems through which the drone sees the world. Higher quality sensors contribute to accurate weapons fire and mapping the environment or perceiving hidden foes.
Processor - Raw processing power. Contributes to weapon accuracy and physical manipulation of the environment, coordination of the body's many systems.
Gearing - Represents the physical systems which move the drone chassis around the world, including both the larger drive motors and the smaller fine manipulation systems. Contributes to physical manipulation of the environment and maneuvering over difficult terrain.
Monitor - Software which sorts and interprets data in real time, the Monitor assists in maneuverability in difficult terrain and helps drive the overall AI processes.
Secondary statistics are used to determine the drone's performance, and are derived from the primary stats.
Perception - Memory + Sensors, perception assist in finding hidden foes, spotting distant objects, or operating normally in difficult environments such as during a rainstorm when visibility is low.
Accuracy - Sensors + Processor, How accurate the drone is when firing a weapon, including the ability to interpret visual and sensory data to determine target's relative position as well as predicting where the target will be at the time of firing.
Dexterity - Processor + Gearing, Includes fine manipulation skills, such as operating a complex machine or typing on a keyboard, as well as trying to dodge enemy fire.
Adaptability - Gearing + Monitor, Indicates the ability of the drone to deal with unusual terrain. This includes moving over rough or broken terrain, climbing trees, leaping a chasm, etc.
AI - Memory+Processor+Monitor, AI is the actual intelligence and reasoning ability of the drone. AI is used any time the drone needs to figure out a puzzling situation, or come up with a solution to an unexpected event.
