Replaying the game at higher difficulty

[patches4711]

I beat the game on easy and unlocked stage select. How do you replay the game at higher difficultys while also working towards 15hr and all upgrade achievements. Thanks for the help

Just restart a new game. You can use your powered up weapons from the first play through. The easiest thing to do is just keep playing the first level and then restarting a new game. Do it over and over and over and you'll have maxed out weapons. Will only take 5 or 6 hours, but will make it much easier to play through the game on the harder difficulties with maxed weapons.

As for the 15 hour achievement you'll get it along the way no problem.
But if it's anything like the Japanese version if you are trying the leave the system running trick don't die. Your time is only stored by checkpoint so if it takes you twenty minutes to get to a check point then you leave the system on for 6 hours then start playing again and die, then after another 5 minutes of playing you end that level you'll only get credit for 25 minutes not 6 hours 25 minutes so don't die.

Simply part for the dont die, just start level 2 when your on the bridge, there are no enemies so it makes for easy pickings and as you said dont die or its 6 hours wait again.
