...after completing it on Normal first. It feels like you have to be reeeally careful all the time because the slightest mishap can cost you your life (just switching cover while escaping from a grenade has gotten me killed numerous times!).
 
So now I only have one trophy left to obtain before Platinum: Completing the game on Crushing. To those of you who have done this, do you have any hints or tips for me that might make the experience easier? I'm fairly bad at these kind of games, and the only reason I even finished Hard was because I tried really hard until I made it (it felt kinda like banging my head against a wall at times).
 
What I've discovered so far that I didn't know during my Normal playthrough:
- Apparently the Guardians' crossbows are very useful against other Guardians
- The explosive blue resin is a lot more useful than I thought, and intentionally placed
- Most difficult encounters give you some sort of advantage, be it a weapon or propane tanks or the resin
 
UPDATE: Thank you everyone for your comments, they've really helped so far! I just finished chapter 18, Heart of Ice, and it's gone surprisingly smooth. For some reason the step from Normal to Hard felt a lot more difficult than going from Hard to Crushing! I also appreciate the video tip on the last boss, but here's hoping I won't have to resort to using it =)
 
UPDATE: I got my Platinum Trophy only moments ago =) Couldn't have done it without your advice, thanks guys! I must admit I played that last boss for a sucker but I didn't use any glitches!
