In the last few weeks, a small security company by the name of Diamondback has been expanding its patrol zones on the South Side. Our officers have been systematically harassed, bribed, and blackmailed by their forces, and our service in the area is starting to decrease. We'd like to teach Diamondback a lesson in courtesy.

最後の数週間でダイヤの名で小さな警備会社は南側のパトロール ゾーンを拡大しています。当社の役員がされて体系的に嫌がらせ、賄賂を渡し、彼らの力によって脅迫し、減少地区に当社のサービスを開始します。ダイヤ礼儀にレッスンを教えしたいと思います。
