The build gun is the default weapon. It can be used to mine T1 and T2 ores and can later be upgraded to the Build Gun v2 to mine T3 and higher ores. When digging ore using the Build Gun, each attempt at mining with right click subtracts from the total resources available in that ore block. This will occasionally generate an ore, but produces a lot of rubble. This rubble can be avoided by Super Digging.
