Prototype 2 Official Sidekick companion app lets you monitor NYZ from your iOS device

Now that Prototype 2 is tearing up home consoles with its weird, mutated tentacle-like appendages, we can focus on the important matter of its iOS companion app.

Prototype 2 Official Sidekick is a handy application which, once downloaded onto your iPhone or iPad, can help you keep track of James Heller's destructive progress through New York Zero.

Interactive level maps covering NYZ's Green, Yellow, and Red Zones allow you to plan your next attack, while filter options let you hunt down collectibles with ease.

Plus, if you enjoy basking in your own glory, the app's trophy- and achievement-tracking capabilities will be right up your self-congratulatory alley.

Finally, anyone looking to uncover the secrets of Alex Mercer's mutations will find some clues relating to potential upgrades and augmentations. For, as we all know, more tentacles = more fun.

A quick word of warning: you'll need to cough up some green if you want to unlock the Green and Red Zone maps.

However, if you want to see what secrets are hidden in the Yellow Zone free of charge, download Prototype 2 Official Sidekick from the App Store now.
