Bear in mind that the Tank O/S Upgrade provides more health points than a level of Endurance on higher difficulties, and hence the former should be on a higher priority.A player should avoid taking damage rather than being prepared to take more damage. Quick-saving frequently can reduce the need of Endurance.

If the player is able to eliminate most enemies without an actual fight, such as using the TC-11 "Brick" Grenade Launcher, Endurance is much less useful.
