O/S Upgrade increases the maximum health by 5 hit points.
- Tank offers very little value for lower difficulty levels. For example, on Normal difficulty with Endurance level 1, the maximum health is 35 HP and each Endurance level adds 5 HP more.
- However, on higher difficulty levels (especially on Impossible), this upgrade becomes valuable due to extremely low maximum health, high Cybernetic Modules cost of upgrades, and only 3 HP increase of maximum hit points with each Endurance level.
