How to unlock the Overkill achievement in Outland - Definitive Guide
Just stand on the second red platform to the right from the Energy Crystal and wait for enough Jellyfishes to come near you and the fire the Beam. most of them is going to be slightly higher than you so you musn't move the beam from left to right, just make it straight left and slowly move the Beam upwards.
Just a little note - while standing on the platform pay attention to the Beam Trap to your right.
I got it on my first try with this method.
Difficulty: Very Easy
Length: Very Short
As the other solutions mention it, when you get the Beam Shot is a great place to get the achievement. I just wanted to add a little clip to show it. Just take your time and wait for the enemies to group close to each other and fire when you're ready.
This one can be done just after acquiring the power. Several Jellyfish will be up in the air above. Start the beam at one side and sweep it along the group. There are other opportunities to kill six enemies at once if you miss this chance. Must be done by one player without assistance if playing Co-op.
You will gain an ability called 'Beam Attack' in the 'City: The City Walls' area (first area of the 'City' Zone). Nearby where you will get this ability, you will find a Checkpoint, an Energy Crystal and a lot of Jellyfishes. Consequently, this is an ideal spot to get this trophy.
Get on the suspended platforms on the right, wait until there are enough Jellyfish enemies in your sight to use the 'Beam Attack' (). If you fail, use the checkpoint and kill yourself.
Notes:
• You can guide the beam with the D-pad or the Left Stick
• Polarity will not affect this move (i.e., you can kill enemies regardless of their polarity)
• The farming spot mentioned for the 'Millionaire' trophy is also a good place to get the 'Overkill' one.
There will be few places in the game where more than six enemies are close enough to each other. These are mainly flying fireflies or color-changing fish.
Lots of flying fish in the fourth Sky location:

There are many flying jellyfish in the fifth location of Eternity:
