I don't understand how people get up to 400-500 HP in like rank 15... While I'm at only 294! Where do they get these huge tanks and powerful weapons?!?! They have swords that do like, 80 damage and guns that do 120 and I don't understand where they're from... Help me plz

You just have to get lucky in the campaign silver/gold boxes, or save up/buy tokens to buy said boxes from the shop. It's tough but that's the only way.

Hope this helps.

Thanks for the help dude

But what kinda stuff am I looking for... Torsos? Legs? Modules?

Go for a good torso first, that's the most important. Then get some better weapons. Modules are not too important at rank 15 although heat and armor will be your biggest concerns at the moment. Play campaign to earn credits, then buy item boxes and hope for legendaries is my advice.

Good luck.
