Em-8ER will feature a brand new server architecture. We won't discuss the secret sauce because we don't know if our experiments will work yet. We're going to be doing a lot of trial and error. But the goal is to allow for very, very responsive shooting, NPC reactions and yes, melee attacks.
In Planetside 2 this was a proposed mech unit. it featured a slow firing plasma gun. I liked the idea of having bespoke frames, afterall, it makes the challenge more interesting.
Just as a side note, Planetside 2 uses client side hit detection than server side for server load alleviation.
