Probably not as there are no more credits. If anything, they could have had it sellable for maybe some tungsten or spare parts. Or you could craft it into a Peng gun that shoots statues or something. That would have been cool.
A Dead Space with no Peng would not be a Dead Space. Even the dlc in DS2 had its own Peng. Agree though we should have been able to sell it or something. At least it's there and there's an achievement.
Not 100% on it but I don't think so. I remember reading from somewhere that if you're playing the level it's found with a partner (14?), once one person gets it, you have to reload the checkpoint so the other person can get it. Based on that, I assume
it can't be shared.
A shame it isn't worth anything. I wanted a huge spectacle surrounding Peng for the last game in the series. I was thinking maybe a giant Peng statue and both you and your partner have to insert your Peng at the same time into the statue and you get tons
of resources or a special suit or something.
