No, you cannot use sticks as melee weapons
The "Swashbuckler"
Melee weapons - usually the
Marauder or the
Vendetta swords
(which can sometimes be dual-wielded, depending on the game rules).
Melee weapons are actually crucial to an HvZ mission, see the
How To Stay Alive section. They don't require
darts, reloading, extra gear such as clips or ways to carry ammo
and so forth. The main drawback is that they aren't generally useful
in games like Jericho or TacOps, and they are less useful in HvHvZ variants.
