If you don't know, I'm specifically talking about the pickup: Barrier.
These barriers all share damage despite what depth and tier they are. An example is the 1-star variant (Tier 1) will do the exact same amount of damage as the 4-star variant (Tier 3) with absolutely no changes. (Have no idea if the status thing I put there is even physically correct, I can't remember)
So I have to ask: Why? What reason is there to have the barriers split into tiers when things like the Auto-Turret Kit doesn't? It's obvious that they can drop at any given depth so why create multiple ones?
For the not-yet-released barrier bandolier, obviously.
