Shadowrun: Hong Kong - Extended Edition

This achievement can be completed starting from the first enemies in the game. If you choose a Samurai build or make your own build, make sure to have points in ranged combat and assault rifles. The more the better - the quicker the killing. I believe team member kills count towards the count as well (they did in the previous game), so assuming you started with an assault rifle, you can rack up 15 kills quite quickly between yourself and Duncan so long as you don't let Carter get any of the killing blows. If you are not playing with assault rifles on your main playthrough, It should be very easy to start a new game on easy with the above method. Otherwise if assault rifles are your main, this achievement should come fairly quickly still, even if you aren't hogging kills.
