Mobile gaming boomed in recent years, but despite this incredible popularity a high-performance mobile device designed for the most discerning gamers failed to materialize. In response we created SHIELD, a portable gaming device marrying incredible graphics and precision controls in an all-in-one portable form factor. Since release, SHIELD has continually improved with the addition of innovative technologies like GameStream and Console Mode, and a growing library of blockbuster games titles like Half-Life 2 and Portal.

Serious gamers want amazing game experiences whenever and wherever, be that at home on their PC, or on the go. This is why we built SHIELD, to deliver spectacular gaming to dedicated gamers anywhere, anytime. Today, we are expanding our SHIELD family with the release of SHIELD tablet and SHIELD wireless controller. Designed with gamers in mind, the SHIELD tablet offers PC-grade performance, crystal clear audio, and the best entertainment and gaming content. Pair it with the optional SHIELD wireless controller and you have the ultimate tablet experience for PC and Android gamers. Designed from the ground-up to be the ultimate gaming tablet, delivering perfect mix of power, portability and performance, SHIELD tablet is the only game in town.
