Augmentation upgrade canister

Augmentation Upgrade Canisters are usable items in Deus Ex. They are used to upgrade any augmentation by one level (except for the three pre-installed augmentations and the Synthetic Heart, which cannot be upgraded).

Use
An upgrade canister takes up one space in the inventory grid. Upgrade canisters can be used at any time by selecting an augmentation in the augmentations interface and clicking "upgrade." Unlike regular augmentation canisters used for installing new augmentations, a medbot is not required to use an upgrade canister.

Locations
A total of 19 upgrade canisters can be found in the game.
