On Terran Mission 1 (Brood War), build an Armory andupgrade your weapons. After you finish upgrading, build about15 Siege Tanks and send them around the outside of the bad Terranbase. You should be able to kill their Command Center withoutproblem.
Hint: Completing Terran Mission 3:
Build about five SCVs to mine for you. Use some torepair Bunkers and Vultures. Then, build about four bunkers ateach entrance, but focus on the left entrance. Then, send a squadof 12-15 marines to attack the Zerg in the north. Remember, themore you attack the enemy base, the less they will have at theend.
Hint: Completing Terran Mission 6:
In the mission where you have to save the Norad 2,build an Armory and upgrade your vehicles to the maximum. Sendfive or six Wraiths directly above your base on the edge. Killthe Mutiliskes and proceed down trough the small pathway to yourright. You should exit to a open area. Proceed south until youare about even with the Norad 2. Quickly destroy the sunken colonyand send back your Wraiths the same way. Then, bring two Dropshipsthe same way with an escort of the Wraiths from before, and bringthem to the Norad 2.
Hint: Completing Zerg Episode 2, Mission8:
The Protoss base to the right is filled with Reaversmaking it very difficult to rush, and the multitude of Cannons/Observersprevents Kerrigan from attacking. Use the following trick to minimizetheir forces easily. Above your bottom-right Hatchery is anotherbase location that is guarded by a Cannon and two Scouts. Bringabout five Hydralisks there to take over the base, then builda Hatchery there. You will notice that just above and below yournew base is another mineral field which is owned by the Protoss.Build many Creep Colonies lining this mineral field. After youhave at least six, turn them all into Sunken Colonies. Wheneverthey try to mine for minerals, they will be destroyed by yoursunken colonies. After awhile, bring in a couple groups of Hydralisks,which should be able to roam through with relative ease.
Hint: Lurker defense:
Play as the Zerg and go to a level with one entranceto your base. Build a Hydrasilk Den, then create a lot of Hydrasilks.Upgrade them to Lurkers. Then have them burrow at the entranceto your base. Note: Wraiths and Comsat can see Lurkers.
Hint: Interfering with CPU mineral production:
Note: This trick works best when playing as the Protossand SCVs and Drones are used. Build a Pylon with Cannons nearan enemy base, but not in it or near its mineral production. Geta Probe and attack their base, unless it is a suicide mission.Immediately after that, run to your cannons and watch the enemyworkers die. If you do this rapidly enough, eventually they willquit making workers and just sit there.
Hint: Multi-player Terran strategy:
Have eight SCVs mining and three gathering gas. Buildtwo Supply Depots and a Barracks, then build at least 20 Marineswith more Depots. Have an SCV build an Engineering Bay. Builda Factory and an Academy. Now add on the Machine Shop and forthe Base add a Comsat Station. Work on a Starport and keep makingmen at your Barracks and Factory. Upgrade your Tanks to siegemode and build an Armory. Build a Control Tower and Wraiths. Havethem learn cloaking and build Dropships. You should be buildingMissile Turrets and Bunkers full of Marines. Build a huge forceof assorted ground and air units. Attack with full force afterusing your Comsat Station to find the enemy.
Find the entrance(s) to your base and build two Bunkers side byside. Fill them both with two Fire Bats and two Marines. Then,build one Bunker behind and in-between the two other Bunkers andfill it with Marines. Build two to three Missile Turrets behindthe Bunkers, then put four to six Siege Tanks in siege mode behindyour Bunkers and Missile Turrets. When in battle, use an SCV torepair damage.
Hint: Multi-player Zerg strategy:
Build the same number of workers as with Terran strategyand start a Spawning Pool. Build 6 Zerglings and start to attackwith full force. Build a Hydralisk Den and keep attacking. Ifyou have not won yet, upgrade to a Hive and get Mutalisks anda Spire. Build a Queensnest and upgrade to a Hive. Move in withZerglings, Hydralisks, Ultralisks, and Guardians.
Hint: Protoss defense:
When you start, build a Gateway and a Forge so thatyou can build Photon Cannons. Then, build a Cybernetics Core sothat you can build the Citadel Of Adun, and in turn Temple OfArchives, and in turn Dark Templars. However, before that, puta Pylon in front of your entrance(s) to your base. Put as manyas possible as far as you can build them. Then, build more behindthem. Next, build Dark Templars in front of the Photon Cannons.You can also put Zealots in front, but Dark Templars and Archonsare recommended. When upgrading, always upgrade Plasma Shieldsfirst to the maximum, as you can upgrade building's Plasma Shieldsbut not attack and defense.
Hint: Zerg defense:Hint: Easy multi-player victory:
First, get the minerals and Vespean Gas you need tobuild a Hydralisk. Then, upgrade Lurker and Burrow. Also buildan Evolution Chamber to build Creep Colonies and turn them intoSpore Colonies. Next, put as many Hydralisks as desired at theentrance(s) to your base. Then, build a few Sunken Colonies behindthem, and behind them build Spore Colonies. When in battle, replacedestroyed buildings and have a few back up Lurkers to replacedead ones.
Once you start the mission send one of your Probes,SCVs, or Drones to one of the CPU's bases and attack it. Keepattacking until all of their Probes, SCVs, or Drones attack you.When all of them approach, run away and they should continue tofollow you. They will not be able to collect any minerals. Watchthem so that they are not destroyed, but continue to make an attackforce. Then, attack them and they will not be able to defend themselves.
