Today saw the launch of ARMA 3 Alpha, and Bohemia Interactive, the developer behind the ARMA franchise, also launched a new trailer showcasing some of the content available in the alpha.

If your haven't been keeping up to date on ARMA, or you are still on the fence about buying it, the trailer should be a good way to put your mind at rest. The video showcases the game's sandbox content, some short helicopter and infantry combat, some scuba diving, and of course, some vehicles, while not so subtly mentioning the size of an island a few times.
