Evil Genius 2: World Domination

I moved my genius (Max) to the bridge that led to the helipad on Crown Gold. I also had Jubei, who has the Windwalk skill to teleport to a target location. I stationed both at the bridge and waited for the agent. Jubei did 10 points per strike and Max 5 per shot. When agent x was below 15 health, I paused and used Jubei’s teleport to move him far far away from the action. Almost immediately afterwards, the cutscene ensued and the achievement was mine.

Thanks for the advice to allow the genius to score the killing blow.
