Beated the level "Hole in One". It follows the same pattern as each previous mission, but the player needs to act especially coordinated and without delay here, surviving at least one very lethal attack in the beginning, before the base has had an occasion to get properly established. Typically I loose a tank in the mentioned early ambush but an on quick built Scout with the aid of already present Rocket Tanks manage to get down the remaining Titans. Apart from that, lots of Maulers to expect eventually. After the rough beginning, when the Extractors are placed and the Constructor is working on upgrading them, I just Gun Tower my base back and forth with a second Constructor, remembering to check out the backyard in case of Archers. Having done that, it all becomes clear. Just mind to deploy the Recycler near the biometal pools. It will leave a lot of room for the battleground where the Scions will leave their biometal Scrap behind, quickening the ISDF development.
In mission resolution, primarily I used Assault Tanks, but popularly occuring Maulers have an advantage above these units. Besides, Assault Tanks are slow and clumsy, tending to get stuck on environmental obstacles, which is just enfuriating to the player. They have quite a good aim though. In the first big mission attempt I was accidentally killed after destroying both Scion bases while searching for the Core Entrance. In the second big attempt I used upgraded Sabres which did good job especially against the Maulers - since Maulers were confused with these fast moving hovercrafts - even though Sabres have terrible aim and it takes a good while for them to get down a solitary unit, particularly when firing en masse. Fortunately it is easier for the Sabres against big structures.
What stopped and frustrated me for a while was the time it took me to come to a conclusion I need to find the Core Entrance myself instead of just with my units. But the futurourbanistic Core Planet looks beautiful with SITE Camera on, I recommend to have a tour that way. Also, despite having destroyed both Scion encampments and taking their biometal pools, they kept pressing with even greater force than before, suggesting they just arbitrarily spawned somewhere.
In mission resolution, what speaks for faster units instead of slow Assault Tanks or Atilla Walkers is that in the end, there is a certain enemy convoy to be destroyed before it reaches the Core Entrance. Slow units could fail to make it on time if the player searches for the Entrance alone - taking first time experience - so this could be tricky if fast units are in disregard. In my case, upgraded Sabres did the job again.
This way or the other, mission done. Braddock wrote a history book about him being a hero with a shadow, but everything ending up well with the war put down. Burns, the Scion Leader sounds like a crazed AI making reproaches to Braddock for attempting to eradicate him, while Braddock mainly focuses on the notion of ending the war he ignited himself. The sides seem to be worth one another, but differ in the level of pretentiousness to myself. Scion clearly has an agenda, probably it was only the Core dependency that kept them on a leash, but certainly they were working on how to bypass that restriction. They were too human to give up the temptation of spreading themselves as a ruling force over the universe.
Someone had to end it and with Scions it seemed just more work with the same result.
