Can I play the game on Normal without missing achievements?

[Ryzel]

Hey! Played this forever ago and thought about it on a whim, I'm shocked to see that it's been updated with new models and all sorts of stuff. I want to play through it again on the current version, but I want to try and get as many achievements as I can. I wanted to know if I play on Normal throughout the game, if I miss out on any secrets/achievements kinda' stuff. I'm trying to avoid like if I beat the game and see a final achievement of "beat all missions on Hard" and know that I have to do every single mission all over again.

If you could let me know I'd really appreciate it!

Almost all of them should be doable on Normal mode. That requirement is more to stop people from getting it on Easy.
