The trademarked logo is for the DS title after all. Sonic and a new character are together in this adventure.Sonic Rush puts you in the roles of Sonic the Hedgehog and Blaze the Cat as they run real fast and attempt to recover the sol emeralds. Blaze isn’t playable in the short demo being shown at E3, but she’ll have her own separate adventure that, of course, often crosses paths with Sonic’s.
The game uses the two screens of the DS to give you a taller view of the action. You’ll be jumping up to get to platforms on the upper screen and falling down to move down below numerous times in each level. This is a pretty cool use of the screens, which really makes the game feel larger and more frantic. The boss fight we saw in the brief demo at E3 takes place on one screen, and it takes on a more polygonal look. Sonic is limited to a small platform in this fight, which pits him against a large, hammerheaded snakelike creature. The polygonal snake moves around in the background, sizing you up for his eventual attack, which is an attempt to crush poor Sonic with his big hammerhead. It’s your job to get the heck out of the way and then jump on top of the head to damage the boss. When you do this three times, the game cuts to some quick alternate camera angles of the final strike. The whole game has a pretty cool look to it and makes good use of polygons in both the Sonic player model and the boss character.
