Go with the Flo. . . - Find a hidden bottle of medicine - Trophy/Achievement
As soon as you have arrived inside the Wolvark Barracks and gone through a corridor of Wolvark's and jumped over some unbreakable crates you will come across a breakable glass door immediately to your left and to your right a staircase of unbreakable crates with a Fuzzle ammo crate and a Chipmunk ammo crate blocking a couple of pathways up and further ahead toilet stolls where with Wolvarks inside. Climb up to the unbreakable crates and smash the 2 ammo crates blocking your path so you can climb up. Once you made it to the top jump to the air vent and keep walking until you reach to the end of the air vent where you will find the hidden bottle of medicine. There's actually 4 bottles, 1 on the floor and 3 on a unbreakable box. Look at any of the medicine and the Go with the Flo. . . Trophy/Achievement will unlock.
