Supreme Commander

Setup a skirmish against a normal AI speed set to normal, victory condition to capture only 50% of the command points.

as soon as game starts start pumping out engineers and start sending them to all points on the map, start with the ones further away from you, there is no need to build anything else you will always win by the time computer reacts. each game will take 3 - 10 min depending on the size of the map, after all engineers are asigned to a target you can change game speed on the options menu to make it go quicker but dont put it on the fastest setting since it will almost always glitch out the game..

I must first thank Gdinut for all his guides because without them this would have been much harder. I also PMed him once when I had an issue and he helped again so all thanks to him.
I believe I have found and easier way to get Controlling Presence, Hold your Own, Cherry Picking, and To the Grave at the same time.
I must emphasize that I didn't get it this way, but I got Controlling Presence and Cherry Picking at the same time so it should be possible.
They are stackable so if you get To the Grave you get the rest also.
Anyway set the winning conditions to supreme, no need to set the no rush, just set the pre base on and fog of war to explored or whatever it's called so you see everything. I can't remember what it's called. Set the winning conditions to 50%. And set your opponent to the farthest away possible so they don't harass you.
Just start building Engineers, I usually build 30, that's way too many for any map.
Set your Commander to build about 10 Power generators.
Then send your engineers to capture the command points. I go from closest to farthest away.
If you are doing a big map, like 10X10 or bigger, have your first engineer build an air base and build a couple air transports.
While this is happening, send your engineers to get all the ones close to you, you should have plenty of time.
When you're finished with that,then set your transports to assist the factory. Then set your LAND factory waypoint to close to the command points you want to capture. Hold down RB and when you see the hand grab it by pressing A, zoom out. The transports will load up 6 at a time and then bring them there. It's way faster than having the engineers slowly make it across the map. I cut my time down from 22-25 minutes to 5-10 minutes depending on the map.
Finally I found a way to minimize the freezing. Instead of it freezing about 70% or the time when saving, it only freezes about 10-20%.
Still ridiculous, but way more manageable.
First always save right before the game ends so if it does freeze, you don't have to do it all again. And you need to make sure it goes all the way to the next screen after where it shows the score at the end of the game.
If it doesn't, SOMETIMES it doesn't count. I had to redo several different achievements again because of this so it's good to make sure you have a save right before the end of every game just in case.
Right before saving, zoom all the way in, save, and then don't touch the controller until it finishes saving. I put mine down. It will save, showing the little circle, it looks like it finishes, but it doesn't, and shows the saving circle again. Then let the game continue for a few seconds after.
You have to do this when saving and at the end of every game and sometimes it will still freeze. It's really frustrating.
Is this totally ridiculous? Of course, but it seemed to help me a lot from freezing.
It also seems to help the longer you play in 1 session.
For example, it usually freezes the first time. Almost every time. Then after the second or third time it wouldn't freeze for the rest of the day if I kept playing.
Anyway sorry this is so long, good luck you few who play this game.

Edit: I forgot 1 thing. On the control point maps, they don't do all the maps. You need to do I believe it is 6 maps as a skirmish. Still this makes the vast majority way easier.
