Myself and a few others are in the late concept and early pre production phase of this game we're working on. The premise goes as follows.
Our project is a type of game that hasn't been done thus far. Our game is a combination of Action Real time Strategies,(see example A), and Third person action games. (see example B) all in real time.
The gameplay consists of 2 teams of 1-4 players.
Each team has one field commander, that plays the game like the RTS we've designed(Real time strategy)
The other 3 players will choose a playable character from a library of hero units. These players will play the game as a third person action game.
The Field Commander will interact with heroes, providing them with goals and objectives, that they have to work together to achieve, putting a high emphasis on teamwork and quick thinking.
