Stamina implant

The Stamina Implant allows the player to increase his Stamina Stat by 10. A voucher must be given to Gerard to receive the upgrade. The player receives an implant from Macil each time a mission is completed.

This item is much more beneficial than the Accuracy Upgrade because the Stamina Stat affects both the player's health cap, and in addition, increases the strength and damage of the Punch Dagger.
