They used PS5 for publicity and exposure, but Sony never advertised their game nor struck a deal with them for exclusivity. It was a choice they reverted.
it always looked like that lol. the only reason anyone is even talking about it is because the devs catered towards PS5 fanboys ahead of the consoles launch. it was only announced for PS5 and promised 4K60fps with raytracing and they talked about how great the PS5 is. so Sony fanboys used this game and the developer's words for theri fanboy warring.
now that the systems are out this game is finally seen for what it really is... a really shitty looking shooter lol
