If you’ve done any research on the achievement “The Dig” you’ll find that the people pumping out videos on it have not been doing the quests in chronological order and have cascaded their game to get techs to beat this achievement. Yes it’s kind of sad but this achievement ends up being stupidly hard.
Yippee-ki-yay: Destroy 50 protoss buildings on hard difficulty
The reason why vikings are so important is because the protoss mass up Colossus, Void Rays, and old school protoss units… all of which are countered by vikings. To cheese it even more most people are purchasing the mercenary vikings so that they are available immediately for this achievement. However, vikings are not necessary, they’re just helpful.
Along with vikings other helpful things are:
- Marauder snare
- Increased bunker size
- Bunker turret
- Turret volley
- Stim pack
- Marine health
- Marauder health
If you don’t have any of these it’ll be even harder for you (however not impossible).
Step 1: Build a Defense
The defense for this mission is pretty minimalistic, what I want you to build is this:
So what I’m doing here is running three tanks two turrets and three supply depots on each side. This is a basic anti-protoss setup. What the supply depots are going to do is make it so that protoss are never going to be able to get line of sight on that outer tanks with their archons, immortals, and stalkers. The depots are going to prevent zealots from owning your tanks. It also means that none of their units ever really have line of sight and get owned.
The two turrets on the outer edge are there to handle the air attack waves. I have turret volley so two is enough for me, you may want to build a couple more if you don’t have it. Once you have this constructed you will be able to defend against every attack wave.
After two waves of attack you will gain access to the cutting laser. This is a high powered weapon that one-shots enemy units. if you want to get the 50 buildings achievement I”d suggest using it on every single enemy unit until you are ready to attack. Your current setup defends against everything but Colossus and Immortals so Colossus and Immortals ALWAYS have to die regardless. You can take up to 3 archons at a time although once again I’d suggest killing every single unit until you have your army.
Step 2: Building the Invasion Army
You are going to want to act a fusion core to your barracks. The core of your army is going to be marines and goliaths (if you have goliaths if not don’t worry about any mechs). Why marines? Marines counter everything, air and ground. Similarly goliaths have equal powered attacks against ground and air making them equally strong. Medics are sort of pointless as they usually just die from colossus spread. You will need a lot of supply depots, a strong economy and a lot of patience. Building this army takes some time to the end that you will want 70 units to attack with.
Why not other mechs? The main reason if void rays. If a void ray is allowed to attack a single target it’s strength gets ramped up to the point where it deals 5x it’s regular damage. Having more powerful units there just means you’re creating bait for void rays. Marines on the other hand have low health pools and with stims can pack a punch.
Yes my strategy is simply to zerg them. Make sure to fully upgrade your weapons and armor for troops and mechs as they will come in very handy. Armor is especially potent as being able to survive three colossus beams is a 50% damage increase against a colossus that can normally wipe you in two.
Step 3: The Attack
Don’t be afraid to lose troops, you are going to lose a HUGE army here. What you do need to worry about is refreshing your attacks. First off don’t attack until a wave comes from the north west quadrant of the map. You will use your cutting laser to wipe it out and then march your troops in. Okay, here’s the important part. This whole time you should have your cutting laser binded to a key, I use 5. When you march in with your army have your troops eliminate his forces and have your cutting laser attack buildings that are in line of sight and in the back. Yes you are going to send this huge army in and watch it get decimated. All the while have your barracks and factory pumping out more units and set the rally point inside the protoss base. After the first chunk of his army is dead chances are you’ll be able to just march through his base with less resistance.
But remember, he is constantly pumping out zealots, stalkers, colossus, void rays, and templars (which don’t have psionic storm) so be on your guard. Keep refreshing your army and keep destroying buildings.
Make sure that you are paying attention also to the types of units that continue to attack you. At this point archons are going to be LoL. The only units to really worry about are colossus and immortals. Immortals because of their high armor and ability to just soak damage from your tanks… and colossus because they’ll wipe out your tanks all the while providing line of sight to other ranged units. Don’t feel let down if your massive army doesn’t get the achievement right away. You have to destroy 50 BUILDINGS so keep the attack up. Keep microing your laser appropriately by holding shift and targeting buldings and units with the thing.
After you’ve completed this achievement you should also try out the Brutal difficulty (if you haven’t already) of this map. The difficulty curve isn’t that much higher. In fact the only new things are one carrier on air waves (meaning you can’t just ignore air rushes anymore) and templar using psionic storm on your troops (which you also cannot ignore). By far this was the hardest achievement I ran into so far as it required ridiculous amounts of micro and macro and constant attention to detail. If you fail at this the first time around don’t fret and try and cheese it like everyone else, it’ll come much faster than starting the game from the beginning.
