The guns in this game must weigh in excess of 20 pounds. They are massive, sometimes bigger than enemy torsos. The way they’re waved about, though, they must be made of light-weight materials. If so, they should shatter like glass or plastic, when shot. I say reduce the HP of guns.
To stop people sniping each other’s guns, they should reduce the accuracy across the board, as I recommended here:
In UFO Defence, and Xenonauts, your ship comes with you and is in the map. They don’t have that here, for some reason. But it meant you could store extra weapons in the ship, and go back to get grenades or such if you needed them. So any theoretical weapon breakage could also be replaced.
