Another battle and another brawler-mech want to facehug you ? With melee combat it won't be a problem, because you can punch his head down or rip him apart with your melee weapon ! Nobody will be stupid enough again to rush into melee capable mech. We are not talking about crude axes or other thrash, imagine how epic will look your melee weapon on your mech just for few tonns of additional weight.
So....brand new Atlas "Can Opener 3000" :

In this topic you can share your schemes of melee implementation and draw some weapons too .
First step in melee combat implementation can be knockdowns and punches. Punches for example don't need to always knockdown, they can just damage armor and structure for a good amount - free hit without heat. Halftorso weapons of that arm will be off for punch duration.
With melee weapon there is many possibilities. "Can Opener 3000" that I imagined can thrust into mech and at maximum speed and momentum damages structure too. It can be 1hit weapon if you won't backpedal from your target after hit Spikes can be ripped from your arm because of great tension, thats why Spikes are not inside arm.
I had other melee weapon idea but its demanding technology level beyond Battletech.
...and yes, Iam Krazy.
