Can I shoot through trees / vehicles / barriers / etc?
Anything that blocks the line of sight will block the infrared beam of your gun, therefore you will not be able to shoot through it. With this in mind, you cannot shoot through tree trunks, vehicles (though you might be able to shoot through vehicle windows) or other solid objects. Leaves, on the other hand, only provide partial cover; the easier it is to see through the leaves, the easier it is to hit somebody stood amongst them.
