Deus Ex: Human Revolution - 1st Boss: Barrett

Difficulty Level: Give Me Deus Ex.
(Hardest Mode).

Was on strictly non-lethal play through.
Exception only to Boss Fights.
Realized I picked up a couple of frags and frag mine.
What better timing to use it and free up some inventory space =D

There are many other ways to defeat him including throwing the barrels, fire extinguishers and gas canisters but I just want to throw some frag rounds since I can't use them on non-lethal play through :P

Just go YouTube and poke around!
