If your software cupboard is nearly bare, and you have £2.50 sloshing around in your pocket then this "questy" flavoured shoot-out is waiting for you.
The urge driving you on to ever more outstanding feats of zapping is the prospect of storming the Birdmen's castle after which everyone can live happily ever after.
I encountered zombies which I had to fend off until daylight returned, followed by a brush with a wizard deep inside a forest. Next I had to pick up tokens under the threat of vampires flapping out from a handy cave before whisking off to a Stonehenge scenario where the hooded priests made short work of me. There are at least two other battle arenas on hand for those with sufficient interest.
A cut above the average basic shoot-'em-up simply because you can amble around a screen with real depth to it. Each setting has its own name, scenery wise and you also get customised lettering. A decent cheapie.
