Zombie Blaster, a DSiWare on-rails shooter, shuffled onto the North American 3DS eShop on 10th October. It seemed entirely suitable for the month that features Halloween, of course, though in our review we awarded 3/10 and said "the only way to really win at Zombie Blaster is to not buy it in the first place".
That concluding line is telling as, it seems, you can no longer buy it from the 3DS eShop even if you want to. As reported to us by an eagle-eyed reader and double checked on our own system — below — this title is no longer available to download on the current portable's store.
We'll try to ascertain what's happening before the upcoming zombie apocalypse at Halloween.
Thanks to Knuckles for the tip.
