I guess, Zark Island can be played also casually right? As I'm also game dev, I don't have much time to play. But casual things, I can find some time. Casual zombie shooting sounds fine to me. :)
Yup. No Campaign mode yet. Just a run and gun zombie shoot em up. Fastest times get posted on a leaderboard. Should take you no more than 10 minutes if you are already familiar with FPS games.
