"CM 505 delivers a punishing rate of fire with incredible stopping power. A massive belt of rounds keeps it shooting harder, for longer."
―Official Description

The CM 505 is a LMG introduced in SAS: Zombie Assault 4. Some considered the CM 505 to be one of the best LMGs in the game before the Expansion Pack update.


Combining decent damage, a moderately-high ROF, and a considerably large clip size, it can devastate non-boss targets and most early-game bosses in seconds. It uses standard LMG ammo, making it moderately expensive to operate compared to Assault Rifles. Combined with a pierce of three, however, the CM 505 can shred crowds of zombies in a matter of seconds.

However, no gun is perfect, and the CM 505 is no exception. It has a large movement penalty of 40%, meaning that the player's movement is severely limited while wielding this gun. Having high mobility, whether through armor or skills, is a must if you plan on using this as your boss weapon, although this is not recommended due to its relatively low DPS.

Also, the high fire rate means that you're likely to burn through ammo quickly, calling for more expenses on ammo (the Field Supplies skill can alleviate this problem, given the 505's monstrous capacity) and more time spent reloading.

You also need to be wary of the fact that the CM 505, like other LMGs, has a sluggish reload time, the second longest in its class. Switching to a pistol, running away and reloading is almost necessary for the CM 505, unless you can take the damage. It is also somewhat rare.

Overall, the 505 is a gun that will not disappoint at low-to-mid levels.
