IGN: Is the cover and sprint functionality still mapped to the same key? If so, why? Is there any way to map the functions to separate keys?

Cliff Bleszinski: We've modified this system to work nicely with a keyboard and mouse configuration without deviating too far from the original Xbox 360 design. The pacing of the game, while fast and tactical, had to remain intact and that meant maintaining certain tradeoffs for the player. Aim and your field of view shrinks, run and you cannot shoot, run and turn slowly, etc… We ultimately default to the spacebar giving the player the same functionality of taking cover, sprinting, and climbing over obstacles while a double tap on the W, A, S and D keys will also perform this functionality. Players can play either way they choose.

Rod Fergusson: And of course, using the controller is still a great way to play.
