Getting all weapon upgrades

[vildere.ninja.MIS]

Is that even possible?
I'm out now hunting crows and seagulls for salvage.
Appearently it has to be done in the same savegame.

As you progress thru the game you can go back to previous areas using the fast travel feature - you can get more salvage in areas you've already been thru and will be able to access areas you couldn't before to get more salvage - there's plenty of it out there and it's not hard to get all of the upgrades prior to the end of the game.

I just can't find it then. I've completed the game with 100% and I'm like 300 salvage short

You should be able to find enough salvage. Return to areas you've been to before and hunt animals again (they refresh each time you fast travel in). Probably you didn't loot enough bad guys as you played. Second time I played thru I am killing no more than four enemies at once and then looting them under fire because only four bodies can be looted at a time, and if you kill more than four you'll still only have four bodies to loot. I got all weapons upgraded before going past the point of no return.

I found it easy enough.
Then again I was pretty nuts about completing challenges and such.

You have to explore the island and backtrack using fast travel to find and reach hidden spots that were not accessible before. Doors with ropes on the front can only be opened after you get the rope upgrade for the bow, wooden barriers can only be passed after you get the shotgun, and so on.
If you only go straight from point a to point b to complete the story, you wont be able get all the upgrades before the final chapter. Going off the main path, exploring and backtracking are the keys.

I'm already finish the game with 100%, all tombs done. I'm searching for salvages loots right now and not find anything to complete the Bows Upgrades (I need Stabilizing Weight and Penetrating Arrows). I search all cenarios, searching for boxes. Didn't find anything yet.

For all, I fight some guys in the Shantytown.

[Quetzalcoatl]

I travel for all stages searching for the last bow part e nothing. Someone can help me?
I do all the tombs. I see enemies respawns in Shantytown and spread for shipwreck beach. The enemies at least can do the last part at loot?
