Adrenaline Rush is a Fallout 2, Fallout Tactics and Lionheart perk. It is also a skill that was to appear in the canceled Fallout: Brotherhood of Steel 2 (skills in this game work like perks do in other Fallout games).
Fallout 2 and Fallout TacticsEdit
“With this Perk, you gain +1 to your Strength when you drop below 1/2 of your max hit points.”— Fallout 2 In-game description
Fallout: Brotherhood of Steel 2Edit

|The following is based on Lionheart and is not part of the Fallout franchise.|
You will gain +1 to Agility and +20 evasion if your hit points drop below half of their maximum and an additional +1 to Agility and +10 evasion, +1 melee dmg if they drop below 25%.
Behind the scenesEdit
The Fallout 3/Fallout: New Vegas/Fallout 4 perk Nerd Rage! is similar to Adrenaline Rush, and uses a variation of the image.
