Shadow Techniques are unique skills that offer new/improved ways to approach each of the game's scenarios. To unlock these techniques, you'll first need to collect scrolls hidden throughout each chapter (see the Shadow Master trophy above). Each technique costs a certain number of points to unlock, with each scroll collected granting a single point.

To earn the The first step trophy, you'll need to complete collect one scroll; for the Almighty trophy, you'll need to do find every scroll in every chapter.

Everyone will have their own preferences as to which techniques they find most useful, but I'd personally recommend the following in particular:

• Shadow Vanish: pretty much essential if you're attempting an all-kills playthrough, this technique allows you to make the body of a dead guard disappear, preventing other guards from discovering the body and so raising an alarm.
• Hidden Knowledge: with this technique, an on-screen indicator is displayed when you press , pinpointing the location of every scroll in the chapter. This makes it much easier to find other scrolls more easily, and so unlock the rest of your techniques.
• Kage: most useful for a no-kills playthrough, this provides temporary invisibility for a few seconds, allowing you to sneak through even closely-guarded locations. You'll also not trigger explosive lights with Kage active. Upgrade to Kage II and you'll make no noise even while running.
• Shinen: an excellent way to dispose of problematic groups of guards - just lure them to the location of your Shinen and remove them all with a single button-press.
