In this tactic you will see how a suprising effect helps you to win the game easily.But here the most important point is the information about your rivals exact location so this means you must know the map very well.Because you will send drones to the enemies’ base at the very early stages of the game.But before that movement you start normally gathering mineral and spawning drones and you must build spawning pool as fast as possible which activates the morphing of the sunken colony.Here you must be very carefully to leak the enemy base and build creep colonies at his creep.The formations are similar so by the surprise effect the enemy will understand the formation lately which carry you to the victory.When you are making creep colony at the enemy base you can spawn some zerglings to aid your offense which realizes your creep colonization.This tactic needs very well recon,micro and macro abilities together with moderate war strategy at the battlefield.But remember that the remaking of this tactic is almost impossible if the enemy is normally skilled player and if he is high skilled this tactic may become useless by some smart maneveurs fro the enemy. So this tactic is not fully guaranteed as everything in the Universe!
