Augmentation upgrade canister

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".
