I just finished the game yesterday, and got RPG inf ammo.
. But my favourit part of the game is against the U-8. Holy crap its gigantic, i also read in the U-8 file (unlocked after chapter) That it was more of those creatures, and even a larger with more shells/armour. Dam it must be hard to fight.
The part i dident like was the Sump, and the cutscenes where you had to press buttons, to run, jump, etc. I ran it on Dx10, so i couldent see a ****, only pressed buttons. Lost many cutscenes there. So i went to dx9 rant the game, not so good graphic then, but still amazing. And i rewatched all cutsceenes.
