Omni-gel is a technological material that can be obtained by breaking down unwanted items, such as weapons, armor, and upgrades. Doing so will usually give you four omni-gel per item. It is designed for use with omni-tools to do electronics or decryption work. Omni-gel can also be used to repair the Mako, though doing so requires the vehicle to be temporarily off-line.
Omni-gel is composed of common, reusable industrial plastics, ceramics, and light alloys kept in a semi-molten state. Being able to render non-essential upgrades and weapons into omni-gel allows them to remain useful while reducing weight. Commander Shepard can carry a maximum amount of 999 omni-gel. Once this limit is reached, any omni-gel received from breaking down items effectively disappears.
By 2185, common security updates prevented the use of omni-gel on locks.
In Mass Effect: Andromeda, Omni-gel is used as main resource to craft Milky-Way tech-based equipment. It is contained in canister. Usually obtained from deconstructing weapons and armors, or by looting and purchase from stores.
- In the Lair of the Shadow Broker DLC when defending the bypassing program required to open the hatch on the Shadow Broker's base, Shepard asks Liara how long the program will take, with Liara responding that she doesn't know. Shepard continues, "Remember the old days when you could just slap omni-gel on everything?" to which Liara responds, "That security upgrade made a lot of people unhappy," explaining omni-gel's absence in Mass Effect 2.
