"A very powerful weapon, capable of destroying entire cities."
Anti-matter bombs are extremely powerful space-to-ground weapons, made purchasable in the late Space Stage. The anti-matter bomb is second only to the Planet Buster in terms of destructive power, being capable of destroying an area that covers roughly one twentieth of the planet, destroying all creatures and structures in its blast range. It is ideal for instant takeover of hostile planets, and does not break the Galactic Code. It also destroys spaceships in the vicinity of the blast.
An effective strategy on Grox systems is to use a Shield and circle over the city until spaceships begin converging. Drop the bomb, and the city and the encircling spaceships will be destroyed. However, anti-matter bombs are very expensive, and you can buy a limit of three from any empire in any given transaction.
