In the 'Welcome To Hope' mission, you will get the 'Get To The Bartender' objective early in the mission. One bone is in the gave already, another can be found next to a dead dog, and the final one is on the far left next to a grave with a cross. Drop all three bones into the gave nearby to activate an Easter Egg. In the 'End Of The Road - The Desert' mission, when Agent 47 must kill his target in the arid desert, there are three bones scattered around the area. This is a reference to the Double Rainbow viral YouTube video. Destroy all the angel statues in the cemetery to have another rainbow appear in the sky, creating a double rainbow. Load the 'Absolution - The Crematorium' mission. Look in the dog cage to see two dogs humping.

At the start of the new area, go right, and walk straight until you see a dog cage. When the mission begins, eliminate the first two targets, then go back to the door that is locked. Load the 'Shaving Lenny - Streets Of Hope' mission. Knock the guy out, and put his body in the dumpster to find a chipmunk mascot costume on the ground that can be used as a disguise. In the 'Hunter And Hunted' mission, look for a man waiting in a dead-end alley. If done correctly, the target will slowly walk to a certain spot, and an ice cream truck will speed by, hitting and killing the target. Grab the sniper rifle from Agent 47's car trunk, and shoot the three vultures in the sky to your right (from the car, looking toward the grave), then shoot the next bird slightly to the left (about the center of the screen), and finally shoot the last bird on the left. All five birds should then fly into the sky and circle the area. They will then be near or on the rusty old car and the fallen dead tree, as well as one right beside the grave. Instead of shooting him, walk toward the five vultures nearby to scare them off.

In the 'End Of The Road - The Desert' mission, when Agent 47 must kill his target in the arid desert, there is an alternate way to kill him.
