What's the best way to gain the achievement in Halo Wars on Mission 7, The Scarab?

[lilmissgrunger]

The achievement is to not destroy any power nodes, what's the best way to do this?
The achievement is on Mission 7 of the Campaign, and during gameplay there are power nodes which you can destroy, and slow the Scarabs head movements.

But the achievement is called Micro Manager, and if you complete the level without destroying a single power node, you get the achievement. Me and my boyfriend have tried so hard to get it, but nothing we try works. Is there a certain type of unit that works best??

Which achievement? Be specific, and i will edit my answer to include details.


Thank you for being specific. Heres your present. A full answer, AND a video if your still stuck. To get the micro manager achievement, * It is easiest to get this achievement by using the "head trick" which involves sending 10 marine squads up to the right side of the Scarabs head. If the trick works the Scarab will not be able to hit your marines allowing you to kill it without needing to worry about it killing your squads, it will go faster if you then send some Cobras up the left side of the Scarab.

* Another way is making many Warthogs and tell them to ram the Scarab. This way, the Warthogs will not attack the nodes and will prowl right into the Scarab. This trick works best with about 15 Gauss Warthogs.

* A cost-effective way, and one that is quick, is to have your two marine squads and Rhinos defend your base. Then, have Sergeant Forge's Warthog and the other Warthog, along with two to four Scorpions upgraded with the Canister Shell. Attack from the left, where the Honor Guard Elite and Grunt Squad are sitting at. From that point on, move up to the Scarab. This is highly advised when the Scarab's beam is attacking the wall. If it's not attacking the wall, then do not move the two Warthogs/2-4 Scorpions up until it is. Here is the video: http://www.youtube.com/watch?v=69eI0wKuBN4


I wish you good luck. And I hope that i really helped. Good luck. Oh, 1 more detail. The achievement is 5G, but really worth getting. Its a achievement that means you have skills.
