Extended curation: The game has some specific achievements (Zero-G Basketball, Shooting Gallery, etc.) that would be considered missable if the game wasn't too lenient with saves [chapters are generally short, anyway]. There's also "grind" achievements that feature getting 30 kills with each weapon, the reason why it's a grind is because the game generally is made towards maining 4 weapons you like and not changing them, due to the way ammo drops work. The best way to do these is to main a weapon you don't want the moment you get it, then ditch it after 30 kills.
Difficulty stackable. Impossible is unlocked from the start, it's essentially Hard difficulty + Permadeath where you can either restart from the beginning or continue but playing on Hard instead. It is possible to combine Impossible and Plasma Cutter Only on the 1st NG Playthrough and get the 100% in 2 playthroughs, but this is a pretty arduous task and there are insta-kill scenarios added on-top. One thing to note: Impossible NG+ is only available if you beat NG on Impossible.
The recommended 100% route is: thorough 1st NG playthrough on Medium [Hard is better to get accustomed to the game for Impossible] where 30 kills with each weapon + other misc/collectible achievements are knocked out, followed by the 2nd NG+ Hard/Easy Plasma Cutter Only Alternative Ending playthrough where you generally should be able to fully upgrade all weapons and equipment (you can equip other weapons,just don't fire them), then followed by the 3rd NG Impossible playthrough.
NG+ features a new set of collectibles called "Marker fragments", collecting them all results in seeing the Alternative ending that is required for the 100% - combining NG+ Hard/Easy with Alternative Ending and Plasma Cutter Only is the way to go.
