A first trailer for Square Enix's browser-based multiplayer action title Crystal Conquest has been released through 4Gamer. Take a look below.
You'll notice that some of the screens of the game appear to have a giant map covering the action. That is indeed a layout of the battlefield, which is set up as a maze of rooms. Players can switch the map between large, where it covers the screen, and small, where it's shown in the upper right.
The screens also show an "SOS" button in the upper right. This is used to alert other players that you need help. Someone will hopefully come to your assistance.
