Unreal Tournament 2004/Adrenaline

Adrenaline is found in red/white "pills" that are scattered across maps in all vanilla game types excluding Onslaught, with each pill containing 2 Adrenaline. Adrenaline is also acquired by killing other players or bots. The amount of Adrenaline you currently have is displayed in the upper right corner of the screen. Once you have reached the max, 100 Adrenaline, you can perform an "Adrenaline Combo". These are activated by tapping a combination of movement keys and grant a bonus of some sort for a limited time. While using an Adrenaline Combo, your Adrenaline will drain, the rate of drainage is dependent on the combo you are using. Once you have started a combo, you cannot stop, so choose carefully!
