Kai Leng is a recurring Cerberus assassin and one of Shepard's most persistent adversaries. He is agile, uses a sword, and has a powerful shield. His fights often involve multiple stages and environmental hazards. Focus on stripping his shields with Overload or Disruptor Ammo, then hit him with biotic or tech powers. Use cover to avoid his charges and sword attacks. He is vulnerable during his recovery animations.

Kai Leng Strategy:
- Shield Stripping: Use Overload, Disruptor Ammo, or Energy Drain.
- Power Combos: Detonate biotic or tech combos once shields are down.
- Cover Usage: Stay behind cover to avoid his sword charges and ranged attacks.
- Exploit Openings: Attack after he finishes a charge or a power animation.
