I've gotten four Prototype ships, with Qirex, FEISAR., Auricom and AG-Systems in Omega Collection, but it seems the last Prototype ship is the one ship that's required to reach Rank 50, which feels like a tedious chore to do them. And I completed all of the Wipeout 2048 campaign and obtaining all Elite Passes. Unfortunately, I'm stuck on Rank 42, and unless I can rank up faster via online, I sadly don't have PS+ and even going through Zones won't make it rank up faster. Has anyone found a way for ranking up to 50 in getting the Pir-hana Prototype ship? It seems completing all the campaign has sadly led me to a dead-end for one such ship.
