Konami will offer its cute downloadable AR tank game in time for the Japanese launch of the PlayStation Vita, for free (or more). AR Combat DigiQ: Friend Tank Battalion, based on Konami's Combat DigiQ remote-controlled tanks, will turn any surface at which you point the Vita camera into a battleground for little tanks -- and you'll get five of said battlegrounds for free.
This isn't a gesture of kindness on Konami's part, however: AR Combat DigiQ is a freemium game, with additional levels available for purchase. Stages 6-30 will be bundled for ¥800 ($10.26, but discounted to ¥500 at launch), and stages 31 to 35 and 36 to 40 will sell for ¥200 ($2.56) per pack.
That might be annoying, but wouldn't you buy more AR Games levels for your 3DS if you could?
