E-102 is a great all-around character, with a lot of unique features that make him fun to play. The most notable aspect of E-102 is the way he attacks, not by stomping on enemies, but by shooting them with his multi-target laser; think of it like a mix of Doom, Sonic, and Panzer Dragoon. As you play with E-102, you'll see him evolve from a Dr. Eggman-following drone, to a hero on a quest to destroy Dr. Eggman's evil creations. As a result of this chance of objective, the later few levels have E-102 fighting a boss robot at the end of each stage!

The wind level gives E-102 a chance to put his gliding power up to use; it's quite nice to glide through the air over a chasm while locking on to several targets. Yes, this E-102 is one amazing killing machine.

As E-102, you skip all the outside parts of Red Mountain and head straight for the lava-filled caverns. Be sure to take down all the points that the game indicates as "hit!" as they'll open up new pathways to help you advance through the level.
