Ok so as you know, those that have played further than the intro... [spoiler]you die, same as the end of the demo, in order to complete the mission and you then find yourself aboard the bunker.[/spoiler] However! Did you know you can find your old items? Of course at any time as you likely know, if you die you can find your body and retrieve it or reanimate it. But once you get back down to earth and you're able to free roam, you can actually go back to the factory quite easily and if you go to the area where that boss fight began you'll find your body and you can retrieve your heavy sword and all the items you had and found during that first mission. I only found this today and just thought this might help a few people, might even save you a bit of money since otherwise you'd have to buy a heavy sword as your secondary weapon.
