Considering what Lenny had to say to us in Chicago as he used Victoria as a hostage and escaped, and when you consider just how much of a weasel he is, you may not be very much inclined to let him live after you obtain the information that you want from him. While you can kill him, you may not want to as there is an Achievement attached to not killing him. Note that there are no Challenges for this Chapter of the game.
Now having said that, in addition to the Story resolution that this brief Chapter provides it also happens to be the location of what is perhaps the most amusing Easter Egg of all in the game - which we cover.
The End of the Road Run-through
The Chapter begins with a CS of Dexter Sr. speaking with one of his research scientists, who gives him a briefing on what makes Victoria special. Just as Dexter begins to celebrate his good fortune, Dexter learns that Lenny has been kidnapped! Dexter starts issuing orders left and right, call the ICA, call the Sheriff, who the CS cuts to playing um, Sheriff games.
As the level begins 47 has Lenny digging his own grave, and interrogating the boy initially results in Lenny showing more fear for betraying his father than anything else. After he tells you what you want to know you have to choose whether to kill him or not. If you do not kill him, and instead get in the car and drive away you unlock the Achievement “Not Worth It” (10G) You left Lenny in the desert.
Items
Rest the game to the checkpoint and then head to the tree and get the buzzards into the air, then head to the rock and get the fifth buzzard into the air, and then shoot them all while they are flying to trigger the Easter Egg – which is going to make Lenny very dead! Cute, right? Best one in the game so far!
