Very nice rhythm, has a sort of ambience feel to it rather than a full on battle theme. Kind of makes me think it more suited for the background of a more horror themed game when you're fighting a large monster or something. Kind of like the final battle against Nemesis in Resi 3.
But yea, ignoring when and where it could be used, this is another awesome theme I've heard from you! You are an amazing composer!
Good day to you good Sir!
