You can also charge up a breath or beam attack - which, in Godzilla's case, can be anything from a quick fireball to a full on beam of red-hot plasma, and aim it by hand with the remote if you're playing the Wii version. Should you and your target both choose the death breath and your beams cross, you'll find yourself literally playing tennis, batting a surge of energy back and forth along the beams until someone misses and gets a skullfull of face-erasing defeat.
Planned but not yet installed in the build we saw are a fierce attack that will give you direct control of a specific body part for a short time (think aiming Godzilla's tail with the remote and you'll get the idea), and grappling, a huge part of the previous games.
Much of the game is still under wraps. For instance, only four monsters have been officially announced: Godzilla 2000, Mechagodzilla 3 (Kiryuy), Megalon, and Final Wars Gigan (the non-powered-up version). However, we can make some strong guesses about what some of the others are. The first clue lies in the names of the four "factions" into which the monsters are grouped: Earth Defenders (like Mothra, perhaps?), Aliens (such as Space Godzilla, Orga or King Ghidorah?), Mecha (Mecha King Ghidorah and Mogera?), and Mutants (Biollante?). Space Godzilla's actually a very safe bet, as Atari's press materials include a render of the character.
