The second mod I played Ended in a giant Shivan fork shaped super-juggernaut blasting through a node blockade.
If there were Ancients involved, it wasn't an INF campaign at all, just a mod based on
Inferno, Solar Wars. Which was a ****ed up buggy mess anyway.
The two Inferno mods you described are two parts of the first Inferno campaign released with INFR1.
The second one could be Solar Wars.
There are many Inferno campaigns/mods now in progress - INFA1(a remake of INFA which is getting close to a release), INFA2(sequel to INFA1) and INF SCP(intended to replace the old INFR1).
The only one that is going to be released anytime soon is INFA1. The others will take a while...
INFA has already been released.
What is in the works is INFASA, and INFA2.
INFASA is an overhaul of INFA. For clarity's sake, please call it INFASA and not INFA1 as INFA1 can be mistaken with INFA.
This is really confusing, I know...
INFR1 = The one with the Nemesis vs. GTVA. Released.
INFA = Short for Inferno: Alliance, FS1-like campaign, already released.
INFASA = Sometimes called INFA1, stands for Inferno Alliance Standalone. Revamp of INFA. NOT released.
INFA2 = Short for Inferno Alliance 2. It's basically a sequel to INFASA. NOT released.
Sol: A History = FS1-like campaign, but with the Nemesis and other EA ships. Technically not an INF campaign, made by an INF fan.
Solar Wars = Campaign based in INFR1 but seriously manked up.
