In Asteroids: Outpost the Quantum Tunneller is one of the four different Tools in the game. This is the larger of the mining tools. In the final game, you will have to craft this tool. It will allow you to mine faster and more efficiently than the Small Mining Tool and will likely allow you to mine larger rocks than would be possible with the Small Mining Tool. To mine ore, just point it at a fallen Asteroid and hold LEFT-MOUSE until the Asteroid disappears.
