The Kritzkrieg is the Medic's unlockable replacement for his Medigun. It is pretty much the same as the Medigun with the exception of a faster Übercharge rate and a different Übercharge. Unlike the Medigun's Übercharge that gives the Medic and his patient complete invincibility for 8 seconds, the Kritzkrieg's Übercharge will make the patient's attacks 100% Critical hits for 8 seconds. This weapon has a 25% faster Übercharge time. Taunting with this weapon will do the Oktoberfest taunt, which is 4.2 seconds long and heals the Medic 11 health, not the 10 health which is claimed in one of the tips.
