Augmentation upgrade canister

"An augmentation upgrade canister contains highly specific nanomechanisms that, when combined with a previously programmed module, can increase the efficiency of an installed augmentation. Because no programming is required, upgrade canisters may be used by trained agents in the field with minimal risk."

- description of upgrade canisters

Augmentation Upgrade Canisters are items in the videogame Deus Ex. They are scattered in secret locations throughout the game, and are mostly rarer than augmentation canisters until later levels. An upgrade canister takes up one space in the inventory grid, and they may be used at any time by the player without the need for a medbot. An upgrade canister can be used to upgrade any augmentation (except for the default 3 and Synthetic Heart) by one "level".
