Yes. I bought the guide with my Metroid Prime Trilogy and followed it through MP2 and MP3 to get the items but I never used it in MP1 for some reason. I spent two hours going to every expansion spot and found 4 missile expansion, and I don't do scans, except for enemies.
Using a guide kinda defeats the purpose of playing Metroid... the whole idea is to explore and find stuff yourself... I'm not using a guide for my playthrough.
Yes, and you can save the state so when I save I don't have to start the entire dungeon from the entrance and get back to where I needed to go. @Kratos: On MP1 I have like 70%+ without the guide. Those 4 pickups that I used the guide for got me up a % or 2.
I once put every cheat on and my computer had a thirty-second stroke. I KNEW it had something to do with that. Leave it to me to not eventually put 2 and 2 together.
