Deus Ex: Human Revolusion -
I grab the XP eBook and hack the computer for the code to the locked gate, 3663. On top of leveling up as I open the gate, I find a sweet praxis kit inside the cage! I grab the pack of energy bars plus some pistols from the weapon locker. I leave the building by going all the way to the top floor and out on the roof for some bonus XP then down the fire escape.
