Strength or STR is one of the basic statistics in System Shock 2.


The maximum level of each statistic is 8. A player can only permanently upgrade Strength to level 6. The last two levels require a combination of the following items/Psionic Power:

Note that exceeding level 8 does not yield extra benefits.

Strength increases the inventory size and the melee damage bonus of a player:

Strength Level Total Inventory Slots Melee Damage Bonus
1 30 0
2 33 1
3 36 2
4 39 3
5 42 4
6 45 6
7 45 10
8 45 15
  • The bonus melee damage is added only after each weapon's damage have been multiplied by any factors that need to be taken in (like the type of enemy attacked, bonuses from researching organs, any particular weapon upgrades, any upgrades of weapon category, O/S upgrades). In other words, the bonus melee damage value itself is not multiplied.

Strength is also the requirement of certain weapons and armors:

Strength Level Items
2 Light Combat Armor, M-22 Assault Rifle, WormSkin Armor
3 Powered Armor, Stasis Field Generator, Annelid Launcher
4 Medium Combat Armor, TC-5 Fusion Cannon
6 Heavy Combat Armor
