The E-99 Bomb is a weapon in Singularity.
The E-99 bomb was created by storing huge quantities of Element 99 ore within the device. The sole purpose of the E-99 bomb originally was for it to be used against the two biggest superpowers in the western world, the United States and the United Kingdom. What players learn during the game is that the device is capable of destroying the entire east coast of America. This makes the E-99 bomb, therefore, a very deadly weapon.
