Pandora Celeste: Pirates & Salvage - Setup & key differences

About Pandora Celeste: Pirates & Salvage, from BoardGameGeek:

Pandora Celeste: Pirates & Salvage takes the winning formula of Action Cards, Agendas and Emergency Protocols which made the original so much fun and adds yet another chaotic twist as a demented team of Pirates board the Ship to pursue a whole new set of Missions in this Expansion to Pandora Celeste. 3 new Pirate characters: Wekka Wabbit, Androidgyna and The Whistler enter the Ship via their Pirate Shuttle (which is formed from the box they come in) and turn Pandora Celeste into a PvP team game which pits the Pirates against (some of) the Crew. Are they on a mission to rescue the Crew, steal the Company's secrets or simply loot anything that's not nailed down? And an expansion wouldn't be an expansion without NEW NASTIES to terrorise the Ship. So enter the Cyber-Slaver on a mission to Augment all intelligent life; the Garr'Goyle with skin of stone; and the Ulaar, a genocidal alien driven mad by the impenetrable armour it has encased itself in - the only way to kill it is by spraying the Flu Vaccine from a MediKit into its ventilation grille. New Crew, new Nasties, new Missions. Think things were bad? They just got worse! -description from the publisher
