Prepare to feel lost. Not in a bad way, hopefully, but let your curiousity lead the way. The lore is spread out, and there’s a lot of backtracking obviously since it’s a metroidvania. Don’t forget to use the map either, it can give you hints where you might be able to go next.
Coincidentally, Metroid Prime 4 announcement trailer is turning 5 on June 13th, although they did scrap everything and started over again. Let’s just hope the games turns out great and the wait is worth it.
