He is feeling left out of the party and dealing with those bad feelings earns you a 1.05 point modifier.
Granted you are not supposed to kill civilians, but hey, here is this civilian dressed in a giant Chipmunk suit leaning out the window of a building? Of course you have to shoot them! And besides it is a Challenge so in spite of the spanking we get from Diana, well, it has to be done!
Since Sniper Challenge was released in advance of Absolution you have no way of knowing that the giant chipmunk suit is actually one of the disguises available in Hitman: Absolution, so of course its presence here, in this mini-game, can be considered disconcerting at best and really really strange at worse...
Chipmunk Suit Factoids for your Entertainment
Executing a Giant Chipmunk
The Chipmunk Suit is classified in Absolution as both a Disguise and as a Secret Disguise, which means that it has the function as a full-disguise, and its location must be discovered by the player. According to the official description in the game, it is “The official company mascot for the world-renowned Charlie Chipmunk Hot Sauce Brand.”
In addition to being rather twisted and sick for a hitman to wear this sort if mascot-type disguise, it offers the player quite the source material for comic relief in the game... Actually upon deeper consideration I realized that there is plenty of precedence for this because, if you think about it, Agent 47 has something of a history of making use of goofy disguises.
In New Orleans while Carnival was underway, during the mission The Murder of Crows in Hitman: Blood Money (which happens to be the series title that I like the most, as it has a sort of instant nostalgic feel to it that is similar to what you end up feeling when replaying Grand Theft Auto: Vice City, which is the GTA equivalent to Blood Money in that series) Agent 47 faces off against the rival professional assassins Mark Purayah II (AKA Mark II), co-leader of the elite group of assassins that were known as “The Crows” and his henchmen – technically that would be henchman Raymond Kulinsky and henchwoman Angelina Mason – a collection of handmade and probably very expensive Crow Costumes are used in that mission.
The Crows were engaged by a group with a history of many high-profile assassinations undertaken at the behest of a rival organization known as “The Franchise” led by former FBI Director Alexander Leland Cayne, that collectively in addition to operating a highly-profitable murder-for-hire business was also dedicated to destroying the ICA, and executing its employees and in particular Agent 47. Although The Franchise employed its own small group of secret clones, it was officially anti-clone in its political views.
Unlike the Challenges in Sniper Challenge which are, for the most part, pretty straight forward and limited in alternative methods for completing each, Absolution follows and embraces the philosophy that there is more than one way to skin a cat, that flexibility in game play and strategy being one of the strengths of the game series, and likely one of the primary reasons for its enduring popularity among gamers.
In addition to having a silly-factor that is literally off-the-charts, the Chipmunk Costume is also the only disguise (secret or otherwise) that appears in two different missions in Absolution – being that it can be “discovered” in both the Hunter and Hunted Mission, and during the Dexter Industries Mission.
If you are bored (or simply curious) you may find it both entertaining and informative to read the “Disguise Focus” Section of the Absolution Walkthrough-Guide on SuperCheats.com with particular attention to the list of and descriptions of the different disguises that are available to the player in the course of regular game play.
