Bunch of keys to give you folks (Ninja proof)

Hello
there are keys for:

-Hitman Absolution Sniper Challenge
-Metro 2033
-Dota 2
-TES V: Skyrim

The only way for you folks to get the keys is by discovering the right combination of serial numbers... which will be scrambled except for Skyrim:

Example:

Key 1: 1111-1212-1313-1414
Key 2: 5555-5656-5757-5858

They can be scrambled like this: 1111-5656-1414-5757-5555-1212-5858-1313

Here it is then... enjoy:
