There’s a greater emphasis on combat in this game, and you can play as characters other than Aang without holding a shoulder button the entire time, which was a major annoyance from the first Avatar outing.
Avatar takes place in a world that’s in the midst of a global war. There are four nations, divided up by some of their citizens’ ability to “bend” (use as a weapon or magic) fire, water, earth, or air. The Fire Nation is trying to eliminate the Water, Earth, and Air Nations to establish itself as the planet’s dominant force. The three nations’ only hope for survival lies in Aang’s hands, a 12-year-old Airbender, who also happens to be the Avatar–the one person who can bend all four elements.
You also get a wider variety of characters. Aang, Katara, and Sokka return from the first game and are joined by Iroh, Zuko, & Toph. You even control Appa for one flying level. You go through levels in a two-person team, switching back and forth between your two characters. There’s a fair variety in the way the stories play, and they do a decent job of covering the plot arcs of the second season. The more extensive roster of characters certainly helps here, as they all play a bit differently. Your unused partner no longer takes damage, and she can attack using the other shoulder button. It’s a bit thematically odd switching from Team Avatar to Zuko since they aren’t exactly allies, but the show does so frequently, and the rule of fun wins out.
The first Avatar game was problematically short, but this one is blink-and-you’ll-miss-it. There are 8 levels of moderate length. The combat is vastly improved from the last game. But quickly devolves into using your melee attack and calling your partner into mop-up or combo. Toph & Iroh, while fun to play, have only one move apiece. Also, be sure to use Toph while you have her; she’s only featured in one level. One final colossal gripe: with all the emphasis on combat, you’d expect a formidable cast of bosses. You’ll get one. You’ll just fight Azula over and over, and that fight is pretty much the same each time.
