The latest get SMART tutorial video for Brink has been released and this time they bring us a lesson on classes.  Having a diverse mix of skills on your team is the key to success and fortunately, you can change your class at any time by heading to a friendly command post.  The classes in Brink offer the typical team-based shooter roles:  soldier, engineer, medic and operative.  The operative’s ability to disguise themselves as dead enemies stands out as a unique and flavorful way to kick the ever-loving snot out of unsuspecting opponents.  With less than a week until its May 10 release, we’re on the Brink of our seats! Cue snare drum and audience groan.
