It's more of a prequel than a Season 2. Season 2 will be out later and will hopefully be the full 5 episode version we would be expecting. This is 3 episodes and as far as I'm aware explains some of how we got to Season 1. If you like the first one I expect you'd still enjoy this prequel.
What you do with achievements?
Of course other people will disagree with my opinion but tbh I only played it to get the achievements which are easy.
Ive yet to finish first 1 about 2 hours in, but have 2nd one downloaded and also the new captain spirit thing gonna play them all this weekend... sad to hear 2nd isnt as good but most sequels like that i guess still worth playing?
I played this and found it quite boring. Not as good as the first one imho.
