Starcraft 2 Bunker Circle Defense Basic Tutorial - Strategy Guide for Newbies

This is a basic tutorial of the Starcraft 2 custom map Bunker Circle Defense

This is my first game so the strategy is probably differ from what you are suppose to do but I still won this game with 2 players so it works well.

Point of Game: survive waves without having over 300 units on map

Strategy: Start off with 2 or 3 Tank Bunkers 1 Missile Launcher. Fill 1 or 2 tanks with flame throwers, fill 1 with electricity units, and the missile bunker with missile launchers. once filled start upgrading units, once upgrades are expensive then switch and add more bunkers and units, then upgrade again once the kills keep up with the upgrades.
