USP (Unique Selling Point) :-

Multiplayer combat in which the players must work together to get through each area. This can also be seen in games such as 'Left 4 Dead' but whilst the players must work along side each other to succeed, in our idea they most utilise each others abilities in order to win. For example, Two players could be playing a ranged defenceless character and a slow tank character. In order to succeed the players must use each other, so the ranged character would hide behind the tank and fire at far off enemies whilst the tank would defend the ranged character and beat off enemies that got too close.
