In this link you will find a match of  Red Team (Matt Cooper) vs Blue Team (David Kim).The purpose of this match of course is introducing the units of Starcraft 2.The game is between Terran and Protoss.Firstly the Players begin recon and then Protoss makes a pylon at the middle of the map which helps him to reinforce his army easily by the usage of the Protoss warp teleport action at pylon energy areas.This new ability changes the destiny of Multiplayer gaming.This point is really very important that by only this ability hundreds of tactics can be derived.By just building a pylon at a higher area in the middle of the map, created a very long pressure period on Terran Player.But remember that Terran means defense which at last win the game by just defending him and consuming the Protoss resources.You will see also in this video the usage of Colossuses they are superior to some kind of units while they are very weak against another kinds of Terran units which makes these units a very special assault machines.You can not use Colossus at every assault type but if you use them at correct place and at correct time their harm will be very very destructive!
