Sins of a Solar Empire Rebelion

Posted on Friday, March 21, 2014

I read on a few forums that people have found 66% off coupons on Steam to get GalCiv2. So I was looking for a coupon for Sins Rebelion. I already have Trinity, so I don't really want to pay full price ($40) for Rebellion.... But I would purchase some of the DLC's as they are pretty cheap and look cool.

Can anyone explain to me what "cards" are on Steam? I'm new to it... I was googling for coupon codes, but evidently that doesn't work... lol I saw some posts about 66% off Rebelion, but not sure how to get it...
