Sprintcor 20 Enhanced EnduranceEdit
This common unlock permanently increases the player's sprint capacity. When not wearing heavy armor, the player can sprint the maximum distance allowed. However, the player's sprint gauge recovers at the same rate, meaning extra time must be spent to recover from a long sprint.
Staminar 9 Recovery SystemEdit
This common unlock permanently increases the player's sprint recharge rate. A player with both unlocks can sprint further, and recover their sprint meter in the same time as an unaided player.
