If you take the expo they will not attack it. I used my first group of diamondbacks to take out the initial train and that expo site, then ran an SCV over and built the CC. Nice, superior source of income.

I built Marines-Medics and diamondbacks. You need to have ~7 or 8 diamondbacks minimum after the 5th wave because of the faster trains.

I just use the MM to intercept the trains, and use the diamondbacks to get the flank to do some damage and run them along with the train. Make sure to micro them away from bunkers so that you can keep doing damage. It did take me a few tries because my autosaves were ta points where my army was out of position for the raven push and I only had 3 diamondbacks when the trains sped up (so I had to let one go and build more diamondbacks out of 3 fact).

At the end of hte game I had 3 factories and 5 rax running.

i didnt get neither silver streak, nor all missions complete achievements even tho i went 8/8 on trains, 3/3 on defilers and 6/6 on diamondbacks.
Is it bugged or is there something special to it?

Not sure if its bugged but I got Silver Streak on my first attempt. It was really easy, all I did was mass diamondbacks and used extra minerals on marines =\

i did it with a big barracks ball and mercs after finding the diamondbacks throughout the map. I found the diamondbacks just were not cost effective. Stim did the same job as far as kiting went on the speed train.

Seige up tanks on the tracks, lol when the train comes. That's what I did, didn't lose a single train on Brutal.

I beat this lvl by massing diamond backs for the trains and leaving a group of marines in the base. But I guess what you have upgraded from the armory and lab matters too.

I've had to redo a few levels on Brutal, but this one I beat on the first try.

I just massed Diamond backs, I purposely let the 3rd or 4th train by to repair my tanks and build more. I had a crew of scv's at the front of my base to repair hurt tanks on the fly.

The last train I had to kill I had 16-18ish tanks and didn't even kill an escort just mass clicked the train to kill it and trigger the mission to end.

Only get 1 or 2 factories for diamondbacks and build 1 bunker in your main. Get marines mercs later on to hold the bunker. Either repair them in between trains or have a few scvs following. Kill train by trailing it and only engaging the back few units (usually tanks and heavy units are at the front). You don't even need to engage the air units if you do it right.

I guess if you expo early they won't. A Raven Auto Turret dropped my expo and some Goliaths attacked the expo on a different try.

I just beat it on brutal after several tries. Spam diamondbacks off of 2 factories, get damage upgrade at the armory. After that it's all micro. You'll want some turrets in your base. Don't bother expanding.

As far as micro goes... It's easy on the first few trains, just target fire the escorts. Stay clear of the bunkers while you fight them and then just kill the train. Make sure you run away the one that gets targeted by the seeker missiles.

Against the fast trains it is a little trickier. Don't bother fighting the hellions, avoid the kill squads and get to the front of the train as early as possible. The Diamondbacks can't really catch up to the train, so you need to start attacking them from the front. When each section of the train passes your group of diamond backs attack the next train. Or put them near the front of the train and move along the track without target firing it. Target firing will cause them to stop as long as they can hit the train. If you have enough Diamondbacks you can use the first technique easily.

You should try not to miss a train until they go back to using escorts. So you only have to take out one of the strong escorts. Here you are better off attacking the middle or back of the train to avoid the banshees and raven in the front. Target fire the escorts before you kill the train.

I did it on brutal not getting any of the diamondback on the maps past the first 3. What I did was 2 fac mass diamondback. When attacking the trains, either attack from the front or the back, depending on which side is weaker. Stay on that side until the train is dead. Keep both facs hotkeyed on 2 so that you can constantly macro. Be sure to attack the trains as early as possible because there are a lot of enemies around the exits.

I found it quite easy with the mass diamondback strat that everybody else apparently did. I also used some goli mercs, and added some rine mercs/rines/marauder mercs because I had a bunch of extra minerals. I always had 4-5 SCVs with my diamondbacks doing repairs

I'm having a lot of problems personally with this level. I'm doing the campaign on Brutal and this is the first mission I've had to try and research online to accomplish successfully. I do not have access to siege tanks.

I believe my problem is mismanaging my Diamondbacks once the trains begin having escorts. People have commented that I should not be losing any Diamondbacks but I always have casualties. In between trains I will go back to my base to repair, but while attacking the train the SCVs never keep pace so I feel they are not worthwhile to keep while attacking because they don't get any repairs in.

How should the Diamondbacks be micro'd on the escorts? I feel like I can avoid the bunkers easily enough but the escorts always pick me apart, preventing me from building a large enough force for the later trains.

Should I focus fire the escort and then go back to the train? Or avoid them entirely be sending MM in first to distract and sticking the Diamondbacks on the train?

you can easily do this mission with only diamond backs + war pigs marine mercs in case a banshee shows up at your base

100% diamond was enough for me at hard. after the third (or fourt) train, I took the expand at top. You put 1 bunker their with some rine in it and you're ok.

Initially, I also had problem with this level on brutal. Heres the few things I found are really important that made it actually pretty easy:

- Get armory and weapons upgrade right when the game start and get lvl 2 weapon when lvl 1 finishes. get armor upgrade too if u can
- try to collect all the money scattered and get all 6 diamondbacks in the map
- theres a expansion to the top left that u should get early just for the gas
- get about 2-4 facs with tech lab, and get 2-4 tanks on the cliff between the top and middle track
- protect the tanks with scvs to repair and also build turrets later on for anti air
- try not to lose diamondbacks needlessly, so u can have more and more
- don't try to attack the train right when it leaves the station, stay in ur base to let ur tanks kills some units off, then chase the train after it reaches ur base
- lastly also important, is to use diamond back to attack either the very front or very back of the train, that way theres less units trying to kill them

I did this mission on brutal by having 2 factories producing diamondbacks and I had 2 bunkers of marines in base. The most important thing is to move the diamondbacks and not attack move them on the trains. Just saying that because I lost once due to that.
