In this cooperative "online action adventure," robots Mar-T and Chip collect "upgradable action parts" to enhance their abilities, according to the official description, so they can survive long enough to find the necessary parts to repair their ship before Lord Krung and his Super Huge Mega Laser destroy them. Along the way, they hope to rescue other robots.
Spare Parts kind of sounds like a robotic Metroidvania crossed with Toe Jam & Earl, based on EA's description. We'll learn more during E3!
