We toyed around with several game interfaces and finally settled on Isometric. This was because the side-on platformer is dead, to put it bluntly. Anyway, the game has changed significantly since its conception - the plot at least has changed completely. Much is made of M-Tex's strong plot and characters. In my humble opinion, characters are an essential part of a good single player game.
Characters are very important in a game to involve and absorb the player into the universe.
In order to further reinforce the depth of the characters' lives, we are suiting each character to the levels that they could best do if the situation was for real. For example, Harry's muscles and general weapons obsession would be useful in a level where you basically needed to frag lots of APUs, whereas Dropout's electronics expertise would be required to locate the pieces for, and subsequently construct, a bomb to blow a hole in a six inch thick bulkhead. In other words, the character you control will be determined by the level or situation you are in. It would be impossible to be able to select any character and still keep the continuity alive. There is nothing I like better than a good story.
