Primary: This mode is all about killing everything in sight. Just keep shooting at the zombies as much as you can. You will earn some money from this game mode but it won't be much. It's more like the basic mode where you can practice killing things.

Dead Ops: In this mode, you will feel like an assassin. You will be given a target that you need to eliminate. The target gets stronger each time so you will need to invest in your weapon before taking on this challenge. The rewards are worth the effort so take time to try this out when you can.

Sniper: As the name suggests, this mode gives you missions that you need to accomplish using only a sniper rifle. It takes a bit of getting used to but you will get the hang of it after some practice. Make sure you zoom in to get a better aim at your targets.

Breach: You will be raiding buildings in this game mode. You will need to be quick and alert in this mode to avoid taking damage from zombies. Be mindful of your ammo as you might end up reloading while you have zombies in your face.
