Deus Ex Wiki

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).


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.


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.


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

  • Due to a scripting oversight, if the player has a full inventory when talking to Dr. Jaime Reyes in Hong Kong and/or when talking to Gary Savage when leaving the MJ12 Sub Base, the augmentation upgrade canister that would be given to the player will drop to the floor instead. This exploit can be repeated (by repeatedly talking to Reyes or Savage) to obtain an infinite supply of upgrade canisters. Because the script also attempts to fill up the player's inventory from the top-left, due to how inventory is handled, it can trigger a critical error and crash the game if over 250 instances are present (stacked on top of other items) in the inventory.
  • The game script indicates that during the game's development, it was planned that if Ford Schick is rescued during the first visit to Hell's Kitchen, he would later provide the player with an upgrade canister during the third visit to Hell's Kitchen. This would have increased the total number of obtainable canisters to 20. However, due to scripting errors, this canister is not obtainable.
