Holy shit, read about those weapons.
By far my favorite of the new offerings is the Ubersaw. Looking more
like a gun from Gears of War, the Ubersaw is stained from hilt to
curved blade in blood, a twisted piece of bad-ass metal. It adds 25% to
your ubercharge after scoring a hit, at the expense of a 20% slower
firing speed compared to the standard Bonesaw. Meant for the more
offensively minded medics--AlexXdude, maldoror, et al--the potential
for ubercharge madness, as well as total embarrassment and disastrous
medic time-wasting, is huge.
The Blutsauger--"The Vampire" in German--looks more like a
blaster than a needle gun. It will suck away your enemy's health and
add it to yours at the rate of three health per hit, a nasty
self-healing weapon. But again, while it sounds superior to the Syringe
Gun on paper, it lacks the ability to score critical hits, making it
more of a defensive tool than anything else.
The Critzcrieg we knew about, but it was no less interesting to
play around with. The gun itself emits a passive yellow glow, and upon
ubercharge, casts a Palpatine-esque lightning around your teammate's
weapon, imbuing him with non-stop critical hits for 10 seconds. Deadly
to be sure, but much like a standard ubercharge, it only stays active
for so long. The charge must be well-timed, and fully taken advantage
of. Unlike the health variant, this crit-uber provides no defense for
your attacker, relying totally on the skill of your teammate. If your
soldier wastes his few critical rockets on the wall, you'll be forced
to beat a hasty retreat, with little gain to show for it.
I'm not sure about the crtizcrieg, but the other two sound markedly better than the usual guns.
