Heartbeat Sensors aren't for pussies. Heartbeat Sensors are for people who play conservatively and don't rush. I camp most of the time and when I rush I use P90 and UMP45. HBS + Silencer = stealth.
FMJ+stopping power FTW?
HBS aren't that bad. I just don't use this lame attachment.
Noobtube anyone? :3
HB sensors are gay.
Thermal scope is way better, and can be used as a HB detector.
