From his belt he pulled out his omnitool, using it to hack in and disable the security system and override the electronic lock. He slid the omnitool back into his belt, exchanging it for his pistol, and pushed the door open.

The omni-tool itself is a combination computer and general-purpose engineering device that fabricates tools and equipment as needed. It acts as a translator, computer, holographic recorder and player, full translation software, and can create lockpicks and any other equipment needed to use a character's skills. An omni-tool can be upgraded with a number of options. Characters start play with an omni-tool at no cost.
