Step 1:
Change your computers date to the 15th of december 2011

Step 2:
Open left 4 dead. Go to your settings and enable the developers console, than type:
map c1m1_hotel versus

Step 3:
Once you've entered the map you can need to spawn as survivors!
if you spawned as infected no problem, exit the map and repeat step 2!
Step 4:
Find some special infected and kill them, if you are lucky they will drop a present.
You need atleast 3 presents to get the achievement.
Be fast! after a few minutes you will get kicked because you are the only player in the match!

Step 5:
Get the achievement!
This took me about 30 minutes to do and was pretty simple.
