Google just upped the ante in the Android-tablet space earlier today with the announcement of their Tegra 3-powered Nexus 7 tablet at the Google I/O show in San Francisco.

We’ve already talked about the Nexus 7’s quad-core Tegra 3 innards. So, let’s switch gears and take a peek at some of the latest mobile games being demonstrated at the show. Two were showcased on stage.

Horn was demo’ed on the Nexus 7 tablet in the Google I/O Day 1 keynote, as a revolutionary third-person action-adventure game developed by Phosphor Games and published by Zynga. The game displays the pinnacle of what’s possible in mobile games with its dynamic and engaging console-quality world. Based loosely on the Old English tales of King Horn, you play as a young blacksmith’s apprentice named Horn who wakes up to find your village overrun by large, fantastic and sometimes humorous monsters. It is revealed these creatures are actually the people and animals from your village transformed by a curse, and you alone have the power to free them.

You’ll navigate Horn along his journey with accessible and intuitive touch controls to walk, jump, crawl and grapple hook through a rich and unique fantasy world. Tegra 3 exclusive enhancements include shadows, physically simulated cloth and dynamic water simulation.

Dead Trigger was also featured on the Nexus 7 in today’s keynote. In Dead Trigger, the world has collapsed due to a strange infection that turns regular people into zombies, and it’s up to you and your arsenal of weapons to take down the undead masses. You can find even more information about the game in our Dead Trigger blog post.

If you’re at Google I/O, stop by the NVIDIA pod at the Developer Sandbox and check out Horn along with these upcoming games – all playable for the first time – coming to TegraZone soon:

Beach Buggy Blitz THD comes to us from the folks who brought you Tegra-optimized games like Riptide GP and Shine Runner. Vector Unit’s latest game is built around an “infinite drive” mechanic that challenges players to drive through lush environments – power-sliding through beaches and volcanos, catching big air off massive jumps, and smashing through totally destructible environments. Tegra 3-exclusive features include lens splash effects and dynamic headlights in caves.

Bladeslinger THD challenges you to play as the hero who’s come home after years away at war only to discover someone – or something – has corrupted everyone in the town. You’ll need to uncover what’s happened and cure the town of this corruption. Tegra 3 exclusive features include cloth simulation, advanced light systems, ragdoll physics and additional enemies on screen.

ExZeus II THD aims to add more depth to the original hit game while providing Tegra 3-exclusive features such as unique weaponry and greater detailed environments. Upgrades available throughout the game will have an effect on your robot’s specs, helping you progress through more difficult levels.
