The last time I'd used betathanatine had been in street battles on Sharya. A full dose, designed to bring body temperature down to room normal and slow my heart to a fractional rate. Tricks to beat the antipersonnel detectors on Sharyan spider tanks. With no register on infrared, you could get up close, scale a leg and crack the hatches with termite grenades. Concussed by the shockwave, the crew usually slaughtered as easily as newborn kittens.
