Killer 7 is to video games what “Memento” and “Fight Club” are to movies. Some will walk away from the experience wondering just what the hell they just played while others will reach a new level of enlightenment. You are an elderly assassin named Harman Smith - the leader of a motley group of assassins, each with their own unique personality traits. There's a gun slinger, a masked Mexican wrestler and a young girl just to name a few. As you delve a little deeper into the tale, you realize that these personalities are actually Harman's multiple personalities coming out. The complexities don't end there as the story becomes much more surreal the longer you play. Some aspects will instantly connect with some gamers, while others will likely lose interest early on.
One thing is for sure, Killer 7's story doesn’t pull any punches. In addition to the main story involving “The Smiths”, the story also involves everything from terrorism to the trafficking of children to viral warfare. To be more to the point, Killer 7 does all it can to earn its “M” rating.
If the story doesn't get you interested in Killer 7, neither will the gameplay. Instead of taking the route of normal shooters, Killer 7 takes a much different approach to the entire shooter genre. Though it looks like a 3rd-person adventure, Killer 7 is actually an on-rails shooter. Paths are pre-planned and leave little room for exploration. This gives the game an almost detached feeling since, except for the shooting areas, you really aren't doing much else other than holding the A button and choosing which path you'll take at the end of a section. As you run through areas, you'll eventually run across members of Heaven's Smile which, without giving too much away, is a cult whose members are able to turn invisible -- at least until you scan them. Once scanned, cult members show up as dark human forms with one or two glowing body parts. Shooting a glowing part results in a one-hit kill while hitting other parts will do minimal damage. Killing cult members rewards you with blood, which can then be used to upgrade the abilities of your personalities.
Between gun battles, Killer 7 throws in a few puzzles that usually revolve around your character's special abilities. For example, Kaede can bleed at will while Coyote can pick locks. Not all of the abilities seem useful at first, but believe me, once you just learn to accept the game's odd atmosphere, even the most illogical things feel logical.
