As soon as the game starts build plenty of Guardian Tanks and some IFV's. Roll in and destroy the enemy base except for any Ore Refineries and Barracks.
Done?
Now, start building up your money and several airfields. Once you've done this begin building up your base to allow use of Cyrocopters and begin building them, and while you're at it, start constructing your Proton Collider.
Done?
Once you have roughly 30 Cyrocopters roll them into the enemy base and start freezing any units spawning from the barracks.
Done?
When you have roughly 30 enemy units on screen, go ahead and save your game just to make sure you can retry if need be. After this go ahead and use the Proton Collider.
*boop*
Achievement unlocked.
Would've really preffered a boosting partner for this 1.
Do this against the Empire as they have no rocket infantry to deal with making this a whole lot easier, just have a MIG handy for the robot drone things that appear from time to time.
You must kill 30 enemy units in a single use of an ultimate weapon.
Non-Boost Method
Play against an easy difficulty opponent. You must be playing as the Allies and it's easier if you make your opponents the Empire. Attack your opponents base and destroy everything but their Ore Refinery and Barracks. They'll continuously create ground forces and send them out to attack; it's easier if you're fighting the Empire as they have no infantry unit capable of attacking aerial units. When this is done you'll want to have 30 Cryo-Copters made and with their ice beam ready. As the infantry walk to your base use your cry copters and have them freeze the unit until all 30 Cryo-Copters are holding 30 separate units. From there you just need to launch your ultimate weapon on the group of enemies.
Boost Method
Find a boost partner and this one is quite easy to do. While building your technology up to your ultimate weapon have your barracks create 30 infantry and have them go stand somewhere on the map in a tight group. When your partner is able he'll launch his ultimate weapon on your units and you can do the same when you're ready.
Can be done alongside "Girl's Best Friend," "Meat Grinder," "Sword Saint," "High Speed, Low Drag," "The Knowledge," "The Spy Who Bribed Me" and "Reign of Terror."
