Step #1
The first step is to buy the operating system cyberware “Biodyne Berserk Mk. 1”. This enables berserk/superhero landing when you hold L1 + R1 / LB + RB.
Step #2
Find a group of low-level enemies standing close together. Next, activate berserk (Hold L1 + R1 / LB + RB) and jump on them. You must kill two enemies in one jump.
And that’s it!
