The largest revelation to come out of this demo is that Metal Gear Acid isn' t an action adventure game like its predecessors. Instead, the game is a turn-based tactical strategy game, with what appears to be some card-battle-like mechanics mixed in. You' ll move Snake a certain number of squares around a map as you try to sneak up behind guards and take them out.

The cards are, essentially, your weapons. We saw cards for most of the standard Metal Gear weapons, including silenced rifles, claymores, and the like. The turn-based game also gives you some other options, such as the ability to crouch out of sight, knock on walls, and so on. When your turn ends, the screen moves around to the enemy soldiers on the map, giving them each a turn to act. Actions like moving and putting certain weapons into play have a cost associated with them, limiting the number of actions you can take during one turn.
