Inferno: Alliance Reborn is a remake for Inferno: Alliance, a FreeSpace 2 SCP mod released back in 2006. Just like its predecessor, INFA Reborn will merge Inferno's typical style with FreeSpace 1's atmosphere.
The Europa/Aurora is the Jovian flagship, based on the GTD Hades. This model is currently out from the modpack, but may be added back if upgraded.
