Japanese developer Treasure is known for delivering action games that start out at a fever pitch and only grow more and more intense from there. The company is also known for delivering high quality with style--not just pure, mindless action--and some game players most recently experienced this in Ikaruga, a beautiful and extremely challenging scrolling shooter for the GameCube and Dreamcast. And while Treasure's most recognizable upcoming game is certainly the next installment in Konami's classic shooter series, Gradius V, there's also a wackier, crazier game coming up in Advance Guardian Heroes--a side-scrolling beat-'em-up that publisher Ubisoft will be bringing to these platforms in about a month. Advance Guardian Heroes is an unexpected sequel to a cult classic Sega Saturn game dating back to 1996, and especially since we're fans of that old game, we were thrilled by the first impression given to us by this new, portable version. To our great delight, we're barely scraping through the game's nonstop, over-the-top fight after fight. (Granted, we're playing at the default "hard" difficulty.)

Advance Guardian Heroes is, in fact, a direct sequel to the previous game. But even those who avidly played the first Guardian Heroes may not recall that game's storyline and cast of characters now that it's close to 10 years later. Suffice it to say that no previous experience with Guardian Heroes is necessary to play and enjoy the sequel, though hardcore fans will appreciate seeing many direct references to the characters and situations from the first game. (They'll also appreciate that, unlike in the original game, the story-based sequences can easily be skipped in this game.) What's more, fans of classic 2D side-scrollers may get the same impression that we did--that Advance Guardian Heroes is an homage to the good old days of gaming. During the course of our time with the game, we witnessed scenes that reminded us of specific moments from other past 2D action hits, such as Strider, Golden Axe, Final Fight, and Darkstalkers. Maybe we're just nuts, but we wouldn't put it past Treasure to allude to their influences in such cordial fashion.

At any rate, the focus of Advance Guardian Heroes certainly isn't on storyline or cheeky references (although it introduces plenty of each at a rapid rate). The focus is squarely on fast-paced, beat-'em-up action and battles against nonstop onslaughts of strange foes. This is where Advance Guardian Heroes is likely to distinguish itself from other similar action games, much to the pleasure of longtime Guardian Heroes fans.

For a portable beat-'em-up game in the vein of classics like Final Fight, Advance Guardian Heroes sure seems to have a lot of depth. Honestly, comparisons to other side-scrolling brawlers just don't do this game justice. That's because Advance Guardian Heroes, judging from the several story levels we played through, is anything but formulaic. Expect to fight tons of powerful boss opponents--sometimes in rapid succession--while at the same time having to perform some death-defying leaps and high-flying attacks as you trudge through countless numbers of standard enemies. Upon first impression, Advance Guardian Heroes' combat system makes fighting even these most basic foes quite fun and challenging. That's because you're capable of pulling off multiple different moves and combos with simple presses of the attack button along with the directional pad. You can also take your combos into midair, which often results in enemies getting flattened into each other, which causes massive damage.

The defensive portion of the game is interesting, too. By pressing the right shoulder button just as you're about to be hit by an attack, you'll execute a fighting-game-style parry maneuver, deflecting your foe's strike and causing him to drop his guard so that you can retaliate. Furthermore, many attacks cause you (or your foes) to automatically block incoming attacks, so that the notion "the best defense is a good offense" ends up being highly applicable to this game. For good measure, you've got magic at your disposal, and you begin your adventure with several spells to choose from right off the bat. Your spells can cause heavy damage to groups of foes, and they can also buy you some time to set up a powerful juggle combo; sure enough, you can press the attack against a foe that has been knocked into the air or flat on his back.

Fans of 1996's Guardian Heroes may remember some of these guys, but we expect you won't need to be a Guardian Heroes fan to like this new game a whole lot.

Also of note, as you take damage (and believe us, you will) you'll build up an anger gauge, which you can use by pressing both face buttons simultaneously. This causes you to go into a hyperfast state, allowing you to dish out major damage for just a short while; it's just the edge you sometimes need to get out of a pinch or vanquish a tough boss.

All this may sound like a lot to learn, and sure enough, it is--for a beat-'em-up game, anyway. Fortunately, Advance Guardian Heroes packs in a helpful, rather amusing interactive tutorial, in which one of the game's effete villains goads you into mastering all of the basic moves and techniques necessary for success. Also, apart from the game's story mode, there's a versus mode for up to four players (they'll each need separate GBAs) and a "training" mode in which you can take on computer-controlled player characters. The fighting-game-style combat actually makes these modes pretty entertaining for some pick-up-and-play action, at least judging by our first encounters with the game's tough and aggressive artificial intelligence.
