Okay, in all seriousness.

Some were cheap, some were free?

I could be joking, but seems Gamers Gate and Green Man Gaming have been throwing sales around lately.

i got one from doing a survey...

'Kay then, thanks guys.

From doing the survey This

seriousness???

Dear sir, welcome to the interwebz.

Greenmangaming has a 75% off sale, and a lot of people had credit left. Also Sanctum: Slums in mainly from the survey on their site.

I've had the DLC for a long time... sucks that it isn't worth buying. DLC does not add much content to the game.

..At this rate maybe I'll have to find someone to get this stuff for me, the added weapons and such looked pretty interesting. Already have Slums, though.

with money

1. The game and its DLC might be on sale. I know it currently is on sale on GMG.
2. The devs gave out free DLC keys for doing a survey a while back.
3. IGN Prime has Sanctum keys. That offer is very old, but still valid; they ran out of the base game and Aftermath, but Aftershock and Violator are still available.
