Single player story mode, customizable vehicles, unique characters with narratives, battle royal, destructible environments. Dats it
There's no way sony is sitting back and looking at how EA is stacking $ off apex legends, blizzard is eating off over watch, and epic is basically being funded by fortnite and isn't thinking about making their own Battle Royale.
Twisted metal, syphon filter, warhawk/starhawk, socom and colony wars would be the best candidates.
A twisted metal battle royal game where you upgrade your vehicle and can fight on foot would be an instant hit. The cast of twisted metal is so memorable, and there's opportunity to integrate other characters from playstation franchises.
Kratos with the chariot, general radec with the mech, aloy with the thunderjaw
