So far everything I have found in this game has had SOME purpose to it. Every item has a use, albeit sometimes it's hard to immediatly recognize. In ACT 2 (the village) I keep finding large cinderblocks, that can be held and otherwise placed much like explosive propane tanks, or stackable boxes. What are these cinderblocks for?
In addition to being an awkward and clumsy weapon, the cinder blocks can be used to break certain environmental objects.
In particular, I believe there was at least one roof top with a skylight, where dropping a cinder block on the skylight would break it, allowing you to drop into the (locked and otherwise inaccessible) building below.
I believe there are far more of these cinder blocks available than practical problem-solving uses (that I discovered, at least).
