Is it just me, or does it seem like, even though Leon and Claire are aware of each other, their Campaigns diverge much more like in 1.5. In fact, a LOT of inspiration from this game comes from RE 1.5 and it is amazing.
This makes me think of how underused the "being infected with plaga" was in RE4. I always thought that at the parts where Leon loses consciousness, after the lake, and while attacking Ada, it would have been rad to let us play through some of the Hallucination scenes from RE 3.5 as a way to help us visualize the duality of Leon's infection.
it would have been a great way to include lost material in a way that is relevant to RE4, both in giving substance to the "infected" angle that ultimately never entered into gameplay in RE4, and it would have given us brief fixed camera horror bits to break up the action even more.
A lot of the hallucinatory RE 3.5 bits took inspiration from Evil Dead, just as ultimately, the final RE4 did also.
I'd shit myself if Leon gets infected in this and you get to play a small sample of RE1.5, hell 1.5 would be a sweet unlockable.
