Supreme Commander 2

You have to beat all the maps in either skirmish or online. I suggest skirmish since you can add 2 cheating AIs to support you and finish the matches quite quickly without much effort.

Copy and paste the list into notepad or MS word and knock them off as you go along :)

This achievement can be done at the same time as "to the victor" and "committed relationship". Keep cycling through maps, making sure to pick the same team, while setting up a skirmish assassination against an easy computer. Depending on the map, either build 3 Land or 3 Air factories. Make 10-15 bombers/tanks and send them at the enemy ACU. Each match can be finished in 5-10 minutes.

Very easy just pick skirmish assassination and can be done without playing (except 1v1 maps) if without playing simplely pick a AI or 2 and put on cheating cybran same team as you so 1 and put an enemy bot on easy uef team 2. Now everytime you start up skirmish which itl make you do every win itl start on the same map simple go down the line. There are 25 maps. Now for fastest results if playing or a 1v1 pick cybran, at start put air factory and make 5 air troops(rb to select all) and then fly them over and attack acu to win. Rinse repeat, should get this fairly quickly if youv played and won on maps you know youv played before skip those, goodluck!
