@ Riot.
The first time through should take you about 9-10 hours. You'll also probably want to go through again to find the Emblems/Treasures that you missed the first time around.
If you played through on Pro difficulty without the infinate ammo, im guessing the game would last at least 12 hours, there just aint enough ammo lying around and youd have to keep restarting from a certain point or loading your last checkpoint.
