I reached a point where the game says the box will give me items level 15-30. but there is an item i want thats rank 11 and is only available in boxes. is there anyway i can still get it? or am i just out of luck.

for reference the gun is "hot shot" is a heat based side weapon.

Unfortunately there isn't a way. However the items at these levels are pretty much useless. While the hotshot may look decent, it only has the one use. There are many more items at a higher level that do much more than this weapon can with more shots. This item wouldn't be helpful at a level 30 mech build, which is ideally want you need to be working for

Dino rifle is pretty decent for its weight. Plus there are quite a few useful specials.

It would be really nice to have a 0-15 level box.

Personally there are some low level items I am dying to get and it sucks that there is no way at all for me to get them.
