From the sounds of it, this achievement requires you to win a versus battle within the first 2 minutes of the match. However, I unlocked this achievement in my first match which last about 2 and a half minutes. So either this achievement is glitchy at the moment or it just simply requires you to win a versus match without going into sudden death.
As for tips on getting this, simply have a nice mix of low power pops with high power ones and just keep the pressure on your opponent. Try to gain control of the barriers so you can deploy your troops farther down the field which keeps the pressure even harder.
