The Mark 4 Drill Bomb is a bomb that drills itself 85 studs ( 23.8 meters ) underground on impact with surface. After that, it will explode, lifting up several pieces of rock, concrete, dirt, and anything on the surface or underground. It was first used during the Second Robloxian Civil War, against East Robloxia. It hit Amazeman City/Storm Valley, with the shockwave of the bomb pushing and pressurizing the flying debris into a dangerous cloud of dust, rock, and brick. The shockwave of the bomb pushed through the city, leaving behind nothing but debris. 17 Robloxians survived, two of which survived unharmed. Millions of Robloxians were killed that day. Since the war ended and despite the Robloxians respawning later, the bomb was banned across the entire planet for it being "too inhumane".
