I'd avoided reading most of the thread because spoilers but I'm a fair chunk through the game
First I absolutely love this game, it's so entertaining because the enemy's and weapon attack combinations are so diverse even what should be tedious is so fucking fun
In anyway I have some hot tech for you if it has not being said yet (highly likely) but to fully utilise it you should have whistle Spawn any mountable machine and be able able to move with heavy guns
But if you save with heavy Gun that you blasted off a machine and then loaf it back up, you will have full ammo even if you saved on empty!
So combine that with being able to whistle a mount and then the be able to carry the heavy on the mountable machine, means mobility is no longer an issue
Again sorry if known
But somebody pls let me know if known as I don't want to read through the thread yet till I'm complete
