Version 3! After playing version one, where a player was ganged up on by a group of other players but was given a greater amount of power to compensate, turned into a bit of a mess that simply didn't work right, I actually managed to come up with a second, simpler system. Version 2 was a step in the right direction but it needed more focus and more incentive to defend your Home Deck. Now you get to draw from both decks and you gain points but get a bonus at 15 points. Now, Version 3 should be a little easier to play. This has a much more team on team feel and is a bit more structured. Players can interact and unlike the other time me and some friends tried to think of a Co-Op 'Two Headed Giant' mode, this one manages to cut out most of the awkward parts. Instead, it's two teams fighting over who has the most cards in a 'Home Deck' at the end of a round limit. Those cards being Problems that they solve. It's explained in what I've written so far. So...Give it a go. Link to Rules Please! Try them out and see what you can do with them.
