There are 6 chapters containing a total of 20 missions, and even once you've wrapped up the campaign, there's a bunch of collectible hidden items throughout Gotham that can be acquired in free roam mode. I won't go too far into the storyline (especially since I haven't seen the movie yet), but it seems like there are at least few spoilers in the game - you've been warned. If in-app purchases allow a developer to release a game for free, super, but it really grates when devs try to double-dip. I already paid for the game, don't nickel and dime me to death. IAPs really don't need to be in $6.99 games, even if they amount to little more than progress acceleration. There's a ton of customizability on this front that can be fast-tracked with in-app purchases.

You also earn credits throughout gameplay that are used on smaller upgrades and consumables. Progression is standard fare as well - beat up bad guys, complete primary and secondary missions, earn experience points, level up, unlock new gear, and improve equipment with upgrade points.
