When Snapdragon processors with Adreno 320 GPUs were the hottest thing coming out of Qualcomm's factories, the company released Reign of Amira to show off the power of its then-flagship hardware. Now, the company is using a similar method with the game's sequel, Reign of Amira: The Lost Kingdom, which is available now exclusively for devices packing the Snapdragon 600 CPU (or supposed to be, rather – I was given the option to install it on my Nexus 4).
The game, which probably doesn't offer a whole lot in the way of good gameplay, looks to be more of a "benchmark" than anything – something to show off what the 600 can do. According to the Play Store listing, it's filled with "stunning graphics and effects, fast-action and episodic gameplay, and richly detailed environments" with unlockable weapons, armor, and "devastating special attacks."
