Primary and Secondary Weapons: All MWII and MWIII weapons are available to use in Zombies. Any that are "XP Recommended" are denoted by the small fire icon, and grant you more XP if used.
Insured Slots: These are weapons you’ve leveled up, added attachments to, and come from the weapon pool of over 100 MWII and MWIII weapons.

Tactical and Lethal Equipment: A selection of Multiplayer Tactical and Lethal Equipment can be equipped as part of your Loadout.
Tacticals: Stun Grenade, Smoke Grenade, Scatter Mine, Decoy Grenade, Shock Stick, Stim, or Experimental Gas Grenade.
