I waited patiently for this game to go on sale on Steam, and bought it for 8 bucks when it did.
But unfortunately I find out that to unlock all the players I either need to grind, or pay another 20 bucks!
I noticed that the game doesn't actually use any cloud functionality, since the servers are down (I can't even do some of the online challenges which give additional points), and it doesn't even use steamcloud to save.
So I found the save files which are in some sort of UE4 format GVAS (?) and they are editable, but editing them causes the game to think the file is corrupted.
This is because the first 0-15 or 0-19 bytes are a checksum, and I don't think there's a way to crack checksums unless I know the algorithm / salt used right?
I'm posting here to try and figure out what some good next steps could be.
I'm a software engineer as my day job (but I do web development), I'm interested in learning reverse engineering but don't really have much knowledge outside of some basics.
Any advice would be appreciated. I could link to an example save file if that would be useful as well.
