MGA is not a standard Tactical Espionage Action game like previous Metal Gear titles. MGA is a best described as a “turn based card stealth action” game.
Instead of equipping creating items and using them, the players have to equip cards and use them.
Using a certain card will use it up; hence players are to strategically plan every move they make, because it costs. The screenshots so far suggests Solid snake and a certain mystery female are playable characters.
Only time will tell if player will be able to control more than one character at same time like traditional RPGs.
