We're adding (and have been adding) new attacks for many weapons, inlcuding the MP11, Katana, Ceramic, Machete, Hatchet, Hockey Stick, Lead Pipe, Baton, and others.
While in this process we are also tuning up damage.
Blunt force damage as a whole has been increased, so look for melee weapons to be dishing out more damage now. I won't give you numbers, but they are definitely more worthwhile in combat.
With the addition of new attacks, and damage tuning, you'll see more reason to raise skills, so you can get better attacks.
If you have any special requests, for weapon attacks. Feel free to post them here and I'll consider them.
