Inferno released a chapter before they decided to add stuff and go with SCP.
We've released 2 Ancients demos, R1, and lots of misc ships over the years. We've released more content than most of the other main campaigns combined.
We ported R1 to SCP as R1.5 however the changes became to great so we decided to redo it all to a better quality instead of hacking in SCP features to R1. I then ported R2 to INF SCP Core as a stand alone project not requiring FS2 to help prevent mishaps with INF Builds.
WDYM? Inferno only has one chapter in it right?
R1 was originally 3-4 chapters long which were going to be released in stages. 1+2 was EA War and Gigas incursion, 3 was Ancients and 4 was something a bit different
(Gargant was supposed to be in 4)
INF SCP will probably be 2 main chapters and several smaller projects like the Gateways and Origin, as well as porting as many FS2 mod ships as I can, which should give you more ships than even Inferno builds can handle if you try to load everything at once.
