Gaming and Adrenaline

Does anyone know of any conclusive studies/research regarding adrenaline levels while playing games and whether or not an "adrenaline rush" is obtainable through gaming, and if so can you link them?

The study I found regarding a true adrenaline rush seems to be removed from Psychosomatic Medicine for some reason.

I looked for everything I could think of in my university's library. Everything seems to point to increases in norepinephrine, but not epinephrine (adrenaline). I wasn't able to find anything on frightening video games, but that would be the best place to look.

I don't know about scientific studies or anything I'm pretty sure you can get an adrenaline rush from a video game. Because I get that or something like that all the time. Whether I'm playing a sports game and take the lead in a big game or something, or if I'm playing a Zelda game or Skyrim and do something epic I get super pumped up!! Lol.

I've never researched the topic, but I'd love to find out where that buzz I get when fighting an especially hard boss in Dark Souls comes from.

What was the biggest adrenaline rush you have received while playing a game? Was it when you Finally beat that pesky boss? When you turned on a nintendo 64 for the first time and saw the 3D??
