Mob Control is such a fun little time-waster on Android, I've been playing it on and off myself. Is the Sbenny.COM clan still accepting new members? Would be fun to team up with people from the community.
Mob Control is a great pick for quick sessions, and I have enjoyed the fast tower defense style battles too. A community clan sounds like a fun way to compare progress and share strategies with other players. Good luck building it up, I hope you get plenty of active members joining in.
