Fun fact: Adrenaline Surge automatically relaods your weapon instantly, which has saved my life more than once. Actually, I did some goofing around on the Citadel firing range, and I got a Geth pulse rifle with extended mags V to fire continuously until it ran out of ammo, by spamming Adrenaline Surge, which reloaded it right when the magazine was getting to 20 rounds.
