Battle Ax is an arcade action-slasher adventure game with a top-down view in a fantasy setting. The events of the game take place in the fairy-tale world of Mercia, where the despotic sorceress Etheldreda rules. Every seven years she sends out her army to swell the ranks of her slaves. Throughout Mercia there is a call for glorious warriors to put an end to the tyranny of the evil sorceress. An elf, a wizard and a robber answer the call. You have to join the campaign of a group of heroes and try to cleanse the world of evil and the evil ruler.
