So, still missing the engineer update. Special wrenches, new unlocks, achievements...
It'll have to wait, I guess.

Quick note: You people have all missed the important bit of the wrangler. Speaking as a rather ambush happy combat engineer, doubling the damage on my (bush) sentry will be wonderful. Especially since every inatentive scout mowed down by what should be an (extremely) deadly little box of (unexpected) pain gives me more critz for the shotty.
