Talk:Punch Through (Mechanic)/@comment-15661029-20130816204307/@comment-13117751-20130817175351

I was dubious about puncture at first, but I realize earlier I was wrong and that it IS working as intended... i.e. punching through "xx" distance of object/enemy and then continuing as normal.

HOWEVER, some objects are not objects at all and instead are rendered as solid boundaries, so to speak, of the map and act as "hard stops" for bullets.

This includes

~"floors" of maps (i.e. you can shoot through gangways that are above a floor but you can't shoot through the floor itself)

~certain barrels (like the one you mentioned in your comment)

~Walls (this includes only the "hard" walls and not the decorative features around doorway entries and such...those can still be shot through)

I'm sure there's more stuff and I'm just finding them as I go along now, but that's the key difference between whether puncture will "work" or not, from what I see.
