Brink is one day closer to release, and this first person shooter is geared up and ready to go. Trailer number 5 out 6 is now out and ready to watch. It details all that you will need to know about the different classes available. For example, the soldier class restocks ammo, etc and the operative can hack stuff. Other class options are also available. This video also explains how the UI in-game works and how you can change classes at anytime during a match.
Class based multiplayer is always very fun and addictive. This game certainly looks to match those requirements.
