Nuke: Oblivion Wraith I

This custom-built Minecraft nuke has been crafted(programmed) and engineered to release a power of apocalyptic destruction that closely resembles the power of a true nuclear blast in the real world.

 When this powerful device is powered on, the nuke begins to charge, whichisa little bit time-consuming to complete, before finally detonating—within this timeframe, the flow of time   in the game of Minecraft actually slows to almost a standstill, which makes this impact actually cool (althouh time stops, if you fail to get out of its range in survival it might be the end!!!). As the nuke explodes, it creates a huge crater and reduces a wide surrounding area to flames.

Its destructive power is so strong(Basically its algorithm) that it has the capacity to penetrate even bedrock blocks. Hence, i would not recommend to place it on bedrock level. 

Have fun…
