There are only so many ways to make a game belonging to the hack'n'slash genre interesting. Deathbringer actually tries to bring in some welcome innovation.
The player takes control of some muscle-heavy barbarian armed with an oversized sword cutting his way through hordes of ugly monsters (or, basically, everything in his path). So far, so non-innovative. The sword actually has a name, because it has a life of its own (actually, it's a wizard who has transformed himself into a sword, but let's not get further into this...). The catch: The sword demands to be 'fed' with blood. So you have to keep killing, because if the piece of metal remains dry for too long, it'll start feeding on the player's character, draining his own life away. Very good idea.
