SAS: Zombie Assault 2/Insane Asylum Premiums
The Lee Enfield is a free premium item that will kill your weak Zombie instantly, however its damage against other zombies is very low. It is not recommended to use on higher rounds as slow rate of fire can get you killed. On early rounds however it is an effective weapon. A glitch seems to exist where the reload speed is almost instant.

The MP7 is an SMG premium item that has a fairly good rate of fire, and low damage (as said in the description). It is a good weapon against the stronger Swarm Zombies and Butchers, but during tough situations, it's high fire rate will empty your clip and only kill the weaker zombies in mobs.

The AA-12 is a premium item that is a fully automatic shotgun that has very high damage and a fair rate of fire. It is a highly recommended weapon for taking down zombies, especially screaming zombies. This is also a weapon with almost no downsides, but its low range makes killing from a distance harder.

The M41A is a assault rifle that fires in 4-round bursts. Although it has a low rate of fire, it is a powerful weapon that can take down strong and weak zombies instantly. This weapon runs out of ammo very slowly and can take down Clown Zombies and Chokers easily.
