I've checked the forums , and I do not see any rules of LMS unless I'm blind.
So let me start.
First of all you're given weapons in the LMS day , why would knifing me allowed.
You have 255 HP with a glock for the first few seconds , now we all know glock sucks unless you can do headshots , so you can just rush right in killing many people with a knife HS or 2 backstabs.
In Space day you're given a Scout Rifle but you're not allowed to knife but I checked the forums and no rules about Space day , unless I'm blind.
So I kinda added up the No knife in space day and you're given guns with extra HP to I guess create my own rule ( Which I know it's not allowed but I still did it , stupid me ) making it no knifing.
