Supreme Commander

Battle Commander

I would recommend contacting the people on the boost list and setting up a session. There isn't very many people playing the online and the chances are too thin to do this alone.

To do this you must lose, you cant suicide your ACU so just run your ACU to the other ACU and turn off the fire button by pushing up on the Dpad. Just swap wins on every map and you will get this one after 10.

Thanks to a tip from a friend before I started this, I can now confirm you don't need another player for the two online achievements. They can be done against the AI in a private online match. At first I had two Supreme AIs on my team, against a Normal AI, but I've found it's not necessary at all to have anyone on your team, as the normal AI is really easy to beat.

Play on Assassination as the UEF(United Earth Federation), have the AI be Cybran, as their ACU has the lowest amount of HPs of the factions. Build an Air Factory, and move its output queue over to the AI's base, you can do that by selecting the Air Factory after it's built, and holding RB and pressing A at the point where you want them to go. So then the Bombers you keep making will automatically head over there and attack the AI ACU. That's pretty much it, I also built some Engineers to help assist to speed up the Bomber production, and build some more Power, but I'm not really sure it's absolutely necessary, as on the fastest game speed the maps take 3-4 minutes at the most anyway.

Here are the 34 MP maps. You'll of course only need to complete 10 for Battle Commander.

Quit outs count, find a boosting partner to play ranked online with. Play 10 diff maps in annihilation mode and have them quit the second the match starts. Quit outs count in this game mode but looks like not in any other game mode that I have found so far.
You will also get the win on all multiplayer maps cheev and win on all annihilation maps on any diff if you play them all and have your boosting partner quit out. If the cheev wont pop play one match and win it.
