Omni-gel is a technological material that can be obtained by breaking down unwanted items, such as weapons, armor, and upgrades from the equipment screen. Doing so will usually give you 4 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 the DLC for Mass Effect 2, Lair of the Shadow Broker, when defending the bypassing program required to open the hatch on the Shadow Broker's base, Shepard will ask Liara how long the program will take, with Liara responding saying she doesn't know, causing Shepard to retort with "Remember the old days where you could just slap omni-gel on everything?" Liara will retort "That security upgrade made a lot of people unhappy," explaining omni-gel's absence in Mass Effect 2.
