F. OS Upgrades

System Shock 2 OS Upgrades: Learn about Cybernetically Enhanced, Sharpshooter, Tank, and more, including their ranks and benefits.

Cybernetically Enhanced

Allows the use of two implants at once. Rank: 1. This is the best upgrade, enabling you to increase any two stats or use any two special abilities by equipping two implants.

Naturally Able

Provides a one-time bonus of 8 Cyber Enhancement Units. Rank: 16. This upgrade is useless, as 8 Cyber Modules is not a significant amount and offers no additional abilities.

Pack-Rat

Adds three extra inventory slots. Rank: 15. This upgrade is completely useless because inventory slots depend on Strength (STR), and if you have a STR of 6, it becomes redundant. You can increase your STR with implants, so this upgrade is not recommended.

Pharm-Friend-ly

Grants an extra 20% benefit from all hypos. Rank: 7. This upgrade is quite good for any agent, with those relying on psi hypos benefiting the most. It may be useful on harder difficulty levels where you take more damage.

Sharpshooter

Each shot with a ranged (non-psionic) weapon does 15% more damage. Rank: 2. This upgrade is good, as the 15% damage increase greatly assists in defeating the hardest annelids.

Speedy

Increases movement speed by 15%. Rank: 11. This upgrade is not very useful, as increased movement speed is only beneficial for running, which is rarely necessary except to escape from certain monsters.

Strong Metabolism

Reduces damage from radiation and toxins by 25%. Rank: 14. This is not a good upgrade because you rarely suffer from radiation and toxin damage, and their effects are not powerful.

Tank

Increases maximum hit points (HP) by 5. Rank: 5. This upgrade is pretty useful on harder difficulty levels when you have little HP. It is less effective on Normal difficulty, as you can increase your Endurance for a few Cyber Modules to achieve a similar effect.
