Do you love Harry Potter -- really, really love him? Because you'll have to if you want to enjoy the opening levels of "Harry Potter and the Deathly Hallows, Part 2."

Like the first "Deathly Hallows" game, the new entry takes on the characteristics of a third-person shooter. That's a reflection on the book and movie's action-heavy focus, but a stark departure nonetheless from previous "Potter" games, which were nonlinear and focused more on spells and discovery than blasting hundreds -- no, seriously, literally, hundreds -- of Death Eaters into oblivion.

That, almost exclusively, is what you do in "Hallows," a brief campaign that drops the preceding game's sloppy stealth portions in favor of wall-to-wall carnage. The game softens its language to imply you're not actually killing any of these wizards, but it's hard not to be amused with (or, perhaps, turned off by) how wildly exaggerated the book's violence is in this incarnation.

Although the stealth portions certainly aren't missed, the straight line the new "Hallows" walks makes it harder to ignore how elementary it is as a shooter. A few diversions break up the action, and the game is good about dropping you into the shoes of a surprising array of characters. But regardless of whom you're controlling, the overwhelming majority of the action -- enter area, find cover, defeat scores of Death Eaters, repeat, repeat, repeat -- is as basic as the genre gets.

Initially, it's depressingly so. "Hallows" begins by putting you in Harry's shoes with a single spell -- Stupefy -- that's essentially the wizarding world's equivalent to a basic pistol. Unfortunately, it's so flimsy that comparing it to a pea shooter is an insult to pea shooters. Using it is boring, and considering the second and third spells you receive are designed solely to cast and destroy Protego shields, little about the combat is exciting early on.

But "Hallows" rallies from there by subsequently outfitting players with magic wand answers for a machine gun, grenade launcher, sniper rifle and even a heat-seeking rocket launcher. It's hard not to smirk at how absurdly crazy the bloodbath gets when these spells are in play, but they're so much more fun than the flimsy Stupefy spell that the complete abandonment of authenticity is completely welcome.

Still, high-powered wizard weaponry can't elevate "Hallows" to anything beyond basic. It's never bad beyond the early going, and that, along with the character diversity and the chance to reenact the Battle for Hogwarts beyond anything the book conceived, is enough to make this recommendable to "Potter" fans. For everyone else, though, it's a much harder sell. Third-person shooters are everywhere right now, and there is no shortage of better options if you're more a fan of the genre than "Potter."

The game's value doesn't help matters. You can put a bow on the campaign in a single dedicated afternoon of play, and the unlockable challenge missions -- which are just story levels with par times and online leaderboards -- aren't an enticing postgame reward. There's no multiplayer content of any kind, and while the Kinect support in the Xbox 360 version of the first "Hallows" game wasn't good, this game shelves the novelty entirely rather than improve on it. (The PlayStation 3 version, to its credit, does add optional Playstation Move support.)
