Endless runners are a dime a dozen when it comes to the App Store, that's for sure. Nearly every single time a new one is announced, it's usually a tie-in to a popular license. Spider-Man Unlimited is one such license, and guess what -- its iOS debut is as an endless runner. But, thankfully, this one's actually quite decent, and on top of that, it's free!
This is a narrative-driven game that's split up into two parts. You can play Endless mode, or you can choose to try out the story mode, which gives you a reason to pursue a path to the end of the level. There are two issues, where you face off against the Green Goblin in one, and issue 2 has you tackling the Vulture and his nefarious deeds. There are additional issues on the way as well.
Running is quite simplistic, and basically the same mechanics you've likely seen before, swiping left, right, up, or down in order to navigate. But this time around you're not simply tethered to the same environments over and over. Sometimes you might even be falling from the sky or a high building rather than running forward. And boss encounters, which do pop up at random, are enjoyable enough that they feel as though you're making progress when you fell them. There's even a leveling system to add to that feeling, which allows you to grind for experience.
The energy system that plagues most F2P titles is present here as well, and if you die too many times you can simply buy more lives or wait about an hour or so to earn another life. There are also some issues with swipe recognition, which can be frustrating when you're in the heat of battle.
Surprisingly, Gameloft's Spider-Man Unlimited is a decent runner with a progression system and narrative tiers that allow it to transcend its status as F2P clone that you've seen millions of times over. In fact, with future updates, it may even continue to improve.
