A First Aid Kit is a medical equipment used to recover from wounds encountered in the field. In the real world they would contain Bandaids and other medial tools.
No One Lives Forever 2Edit
First Aid Kits are one of two ways to heal from damage within NOLF2. Bandaids are a second option if found. The First Aid Kit recovers more health than bandages.
Bandaids can be found in certain locations on missions or randomly by searching fallen opponent. However First Aid Kits are not found while searching.
Like NOLF2, First Aid Kits will heal a larger amount of health when compared to bandaids. There are also found in various locations on missions.
