MET2000 and Tsunami probably have some adepts, even if not a lot, and 10000 Daggers may also have cybered operators. It depends on how typical you want the character to be.
A Japanese adept may feel more at home at Tsunami, and a cybered Turkish would work for the Daggers. I actually find nationality to be somewhat more flavorful, and would use the following guidelines:
- German, Polish and Scandinavian mercenaries at MET2000
- Turkish, Ukrainian, Georgian, Lebanese and Syrian mercs at 10,000 Daggers
- Chinese, Vietnamese, Malaysian and Filipino mercs at Combat, Incorporated
- Japanese, Korean, Australian, Fijian, Tongan and other Polynesian mercs at Tsunami
Nothing like the look on the face of players who expected a team of tidy Japanese human mercenaries and encounter a squad of tattooed Fijian orks and trolls with the latest ware from Chiba.
