The Mystery Box gives melee weapons aswell. Round 1: Default Knife

Off Wall:
 * Bowie Knife (can slash more than one Zombie)
 * Sickle
 * Machete (one in the box to, which duel wields)
 * Brass Knuckles

In box weapons:
 * Ballistic Knife (can duel wield with Sickle)
 * Takeo's Katana
 * Pitchfork
 * Broken Vodka bottle
 * Lightning Sword (Melee version of the Wunderwaffe, melee Wonder Weapon)
 * Dagger (duel-wieldable)
 * Dagger of Healing (Stab a player to revive them)

Juggernog, Quick Revive, Stamin-Up, PhD Flopper (in the Lightning Sword's case, its useful), Double Tap (slash twice as fast) all appear.

Deadshot and Speed Cola don't return for obvious reasons.
