Update: Here's the recently published trailer.

Amazon Game Studios has released a free preview of The Unmaking, an impressive looking game where the hordes of enemies you see on-screen are powered by Amazon servers. Your job is to defend your castle by blasting and burning wave after wave of bloodthirsty foes using siege weapons and magic spells alike. The catch is that you need to have a Fire HD 6, Fire HD 7, or Fire HDX 8.9 to enter the battle.

By rendering enemies remotely, The Unmaking takes the burden of the experience off of your portable device, allowing it to render far more opponents on-screen at a single time. The downside to this is that an internet connection is required at all times to play. Not only that, you're going to want a solid connection to your router, and you might want to cut down on the other activity taking place on your network. Congestion can affect the quality of the experience.

The Internet requirement may be a bummer, but at least this time it's there for more than just checking your license. The Unmaking preview is free until the end of January, giving Amazon plenty of time to test things out on its end—I mean, giving you plenty of time to see if this is a game you would eventually want to buy.
