What is an Offer/Survey?

Completing an offer or survey isn't hard, takes less than 10 minutes at most, if a survey doesn't unlock the code simply try another survey while you wait to see if the others unlock it.
Does it include all DLC Maps?
Yes, each code will include all current and future DLC maps.
Do the codes include NukeTown and Giant Bonus Map?
Yes but Only for PC/Steam and PS4/Xbox One.
Why must you complete a survey?
In order to prove that you are not a bot (code scraper) and to keep the codes from being overused we require a simple survey completion.
The Surveys come from our advertisers who are the ones paying for the codes that you the visitors are getting for completing the advertisers surveys.
