Like most games we've played from Polish-based City Interactive, Battlestrike wallops you with audio. There's a lot of it, and from the pitter-patter of rain to the sweet little birdies in the trees, the "thunk" of a bullet hitting some part of your fleshy body, and the sub-thumping smash of an exploding munitions factory, it's all good. Each weapon in your arsenal sounds distinctive, and that's good too.
