Computer Use is one of the skills you can upgrade when levelling up in both games. It allows a character to slice into a computer with computer spikes to (for example) overload computer power conduits or disable sentry droids. With every 4 points in Computer Use comes a slight decrease in spikes needed to do a task on a computer. You can improve the skill with Gear Head/Improved Gear Head/Master Gear Head (+1, +2, and +3 respectively), the Interface Band (+2), the Interface Visor(+4), the Advanced Agent Interface (+7), Infiltrator Gloves (+4) or the Calrissian's Utility Belt (+3). Droid exclusive improvements are: the Computer Probe (+2), the Advanced Computer Tool (+4), Universal Computer Interface (+6) and the Advanced Droid Interface (+7). This is one of the most important skills in the game.
