To those that have finished dead space...

Once completed, can the game be restarted while retaining all your upgrades and such? I ask because I read that you cannot fully upgrade everything on just one play through, so this leads me to believe you can carry over your weapons and fully upgrade them on multiple play throughs?

Hope so, I'd like to see what my plasma cutter does when completely upgraded, it's pretty bad arse with only minor upgrades,I can picture it slicing most things right in two when fully upgraded.

Mmmmm... dismembered Necromorphs, aghghghgh - Homer Simpson

Not trying to be mean but... You could have just figured it out for yourself? I mean you have the game... Or at least have easy access to the game.

If it was a good game you would replay it regardless. I havn't played it yet though, so I can't say.
