Some rather nice tunes that fade in and out as you move between the game's different regions. Voice acting is decent, too, although some dialogue exchanges are missing voices, for some reason.
F.I.S.T. is a nice-looking game, its environments and fuzzy animals lavished in a lovely bit of detail. Some dodgy lip sync lets the side down somewhat, but all in all, there's an admirable depth and richness to the game's dieselpunk style.
Once you've acquired the double jump and the ability to pounce off walls, you'll be leaping all over F.I.S.T.'s levels like a pro. Intricate combo-based combat and a nice drip-feed of mechanics keep things fresh from beginning to end. Vitally, it's fun.
Save for one or two irritating segments, F.I.S.T. is a well-made, entertaining way to spend 10-15 hours or so. Like any good metroidvania, there's ample replay value to boot, as you make your way to 100%.
Locating every collectible, maxing every stat, and unlock every skill will take a long time, as will performing some of the trickier combat-based objectives. This is a rock solid trophy list, though, with a good spread. Nice.
