I played the Steam version of Grey Goo a long time ago. A few months back or so I wanted to start playing again, but my old savegames where apparantly gone. I figured they were lost when I switched to a new PC (well, technically it is still all on a more or less exact copy from my old hard drive that moved to an SSD and then later into a new PC)
Today, on awhim, I tried playing a game, and this time Steam informed me that the local and cloud state of my savegames was inconsistent. I restored the ones from the cloud, happy I could continue where I left so long ago.
The savegames do appear in my list, but I can't actually load them. Some googling suggests that the update containing the Shroud made the old savegames incompatible.
But I really don't feel like playing through all the missions again, I really just wanted to finish the storyline and then try the addon with the Shourd.
Is there a way to get the savegames working again?
Or Is there a way to get savegames from the later mission elsewhere?
Or is there a way to get the campaign in state where it thinks I did the missions I already did and let me just restart the last mission I was playing at?
I think the last missions I played were Barricade and The Aparture Device (at least going by my old savegame list).
