Hello!
Extra items have been finally included in the Steam version of Unepic.
They are a set of special items that are sold by Gualix, a goblin seller in the bottom/right room from the central box.
Instead of coins, these items are purchased using "unepic credits", that is a special currency earned by completing challenges.
This new currency is shown in the top bar next to the coins icon.
In the challenge section of the menú (menu > challenges) you will find how many "unepic credits" you can earn by completing them (only visible in those challenges that have been already discovered).
Once you complete a challenge, all your characters (the one you are playing with, the ones you have saved in the cloud, and the ones you may create in the future) will be rewarded with these "unepic credits". So the more challenges you complete, the more "unepic credits" will all your characters have.
This means that if you earn 100 unepic credits, all new characters will start with those 100 credits.
If you spend them purchasing a special item, only the current character will lose the "unepic credits" needed for that item. All other characters will keep untouched.
Finally, if you already completed challenges, you will automatically receive all corresponding "unepic credits".
Well folks, hope you enjoy them!
