I remember playing this game on an Amiga. I have no idea what it was called.
That looks like Golden Axe; it's a Sega arcade game ported to home computers including the Amiga by Probe. Details: http://www.lemonamiga.com/?game_id=463
Impressive that you were able to find the image without knowing the name of the game. If you paste the image URL of your post above into Google's image search, Google's guess will be "Golden Axe II".
