I recommend co-optimus.com. found tons of games there I did not think had co-op to start with. Use the filters to find what kind of game you are looking for.
Dead island and dead island riptide, entire campaign can be played with 4 people (they can join, leave whenever they want and use their character local too), "open word" (not that big) zombies everywhere, and quite cool story line. I think I completed the game already 3-4 times with different friends. Around 20 hours of main quest content, can take a lot longer if you just spend a lot of time fighting zombies, controller is recommended.
EDIT: Alone game is boring AF imo, together, lots of fun.
