I was wondering why the sword isn't in any of the minigames that I join on servers. It might be because it doesn't do much damage, or that you can't get close enough to anyone with a gun, and do enough damage fast enough to kill them. So, I thought of having an assassin's knife, a smaller melee weapon than the sword, and has a one hit kill.
This could make deathmatches much more interesting with the addition of sneak attacks. Say some sniper is in his fort, not paying attention to what gets in. Someone finally get annoyed with his constant kills, sneaks in, get behind the sniper, and takes him out with this knife!
