Now, developers are starting to preview actual products. One of them, Directive Games based in Shanghai, China, has come forward with a preview of an augmented reality game that will take advantage of ARKit's surface detection tracking.
The Machines, described as a "moba-inspired AR PVP game," tasks players with building an army of mechanical soldiers and going to battle with each other. Players deploy up to four robots at a time onto an AR battlefield, projected onto a tabletop, and proceed to attack as programmed.
A YouTube video demonstrates the action, and also shows indicators for in-game currency, presumably for upgrades (and assumingly available via in-game purchase).
According to tweets from the developer, the game was designed using ARKit and Unreal Engine 4.
A release date is not available, but we can assume that this will not arrive until iOS 11 and ARKit are publicly released this Fall. Those interested in updates can sign-up at the game's webpage.
