Get Every Serious Sam Game for just $20

Seriously a good deal.

Amazon has a serious deal for Serious Sam fans with the Serious Sam Serious bundle.  Seriously.

For $20 dollars you'll own the entirety of the Serious Sam games available - that's 6 games plus some DLC - all available digitally so you don't even have to put on any pants.  

So I lied, the first Serious Sam game is missing in it's original form, but you do get the HD variety.  Almost every game supports co-op except for DD and The Random Encounter.  Go get it while the getting is good, and support Co-Optimus in the process!
