Few fictional weapons can drum up their own cult following. The cadence and rat-tat-tat ruthlessness of Halo's Battle Rifle is unmistakable no matter which side of the barrel you're on. It's a death sentence in the right hands, punctuated by an ellipse of bullets ... and painfully described in overwrought, armament love letters that say things like "ellipse of bullets." As far as iconic Halo bits and pieces go, the Battle Rifle seems almost as inextricable as Master Chief.

And yet the cyborg with humanity at heart skipped enough games for Microsoft to make a big deal out of his return in Halo 4. The new (ish) franchise custodians at 343 Industries are in a tight spot, where they have to shape a message not only around what's new, but what's coming back. The Battle Rifle's return is an easy way to establish the latter, then, especially to those fans who couldn't wrap their heads around the weapon's disappearance in the first place.

Speaking to Joystiq in an interview last year, former Bungie game designer Jaime Griesemer saw the weapon as a piece of deadly nostalgia. "It's not just a weapon, it's the weapon," he said. "For a skilled player, they spend most of their time using that one weapon. If you never miss, it's the most effective tool in the toolbox. So for them, Halo 3 is the Battle Rifle. All their Halo emotion and experience is tied up in it. So it isn't surprising to me when people react that way."

How daunting must it be to work in a space where a video game gun can reach beloved status? It's no wonder Microsoft is being sensitive and cryptic about Halo 4, which introduces what could be the biggest, most widespread (and controversial) change to the multiplayer in years. According to 343, Halo 4 will add customizable loadouts and abilities that are unlocked through a progression system.
