How to walk faster and sneak quieter

This describes how to increase the character's walking speed and make them quieter using the

Find the hidden coins

To increase the speed at which Wilt, Arno and Siska move and reduce the amount of noise they make while sneaking, you need the coins hidden in each level.

There are 20 coins per level. You can find them in out of the way rooms and corridors by using your torch. Shine your torch over an area to see if there's a coin then walk over to it and click the coin icon to collect it.

Upgrade characters

From the main menu select "Progress".

Here you can spend the coins you've collected to increase the speed and reduce the noise of characters.

You can do this up to 4 times for each character with increasing cost for each level.

Does anybody know how to make full upgrade of all characters (for Ultimate team achievement)? For full upgrade I need 150 coins but there is only 140 coins in 7 chapters.

odd use of the word 'torch'.

Wow I did not know that

You saved me a bunch with this, thank you!!

However, it should also be mentioned that when visiting the Upgrades Menu in the Main Menu during gameplay, the player will restart at their last check point once they go back to their game!

And, without giving away any spoilers (at least I hope I'm not), I found that fully upgrading Wilt was the most valuable; and I tried to upgrade Siska and Arno as much as possible up until the end - and everything turned out just fine!

So, I hope folks won't stress too much when decided who to give the coins to for upgrades...
