Well, playing the early levels and unlocking stuff again in the new Pacific campaign made me realize this. New equipment (like explosive packs, big grenade pouches, and even pistols) are also unlocked when you level up, however, unlike regular weapons, they don’t show up in the Campaign progression tree screen.
I believe this should be changed, not only to make the Campaign progression screen more informative (and help prevent people from forgetting they unlocked all these cool new equipment), but also to give even more encouragement for people to level up, and thus play the game (i.e look at this new stuff I can also unlock at these next levels).
Here is a screenshot showing the level required for unlocking some new equipment:
But notice how the Campaign Progression tree screen doesn’t show any of these new equipment unlocks:
I think this should be changed!
