Starcraft 2: Wings of Liberty Mission 10: The Dig
Mission is fairly simple. You start off with a few marines/marauders/medics and after defeating 2 zealots and 2 stalkers you get 2 siege tanks to destroy a few photon cannons.
After you destroy them, the game will teach you about siege mode.
Go a bit further ahead and you will be given control of a base. The game becomes a last stand mission now, like "Zero Hour"
There are 2 ways of going with this: Either build bunkers, marines, medics and siege tanks OR build a few ghosts and make a wall.
4-5 ghosts should be enough. If you have the upgrade that allows them to stay invisible forever, you can just cloak them and build a wall like that. The protoss will not be able to progress because they do not like to use their observers and detect the ghosts. You will need ~8-10 ghosts to cover up both entrances to your base.
After some time you will be given control of the lazer drill, which you can use to gather the 3 protoss artifacts on this mission.
After killing the photon cannon with your ghost (he should have more range than the cannon, if you don't have the upgrade that gives him range, you will probably need other units or you can just nuke the cannon)
After you destroy the temple with the lazer drill, a protoss artifact will come out of it.
There is a second temple with an artifact right below the first one.
The third and final artifact is in this possition.
Also, if you're playing on a difficulty higher than normal, you will need to build a LOT of turrets around the lazer, as the protoss send out air units against it once in a while.
After you've destroyed the xel'naga temple doors, you will complete the mission.
