Like all prototype weapons, the SC400S is the best in its class, surpassing every other SMG in terms of damage, accuracy, stability, magazine size, and is roughly on par with the Vector in terms of rate of fire. Like any other prototype weapon, it features and integral (undetachable) silencer.
The SC400S ties with the SC-IS Shotgun in purchase price and, just like the shotgun, only requires the first upgrade for Charlie's Lab to become purchasable. These factors make it a decent substitute for the in every regard even better SC4000, however once you have enough money to fully upgrade the Prototype Assault Rifle, any redeeming value of the SC400S ceases to exist.
- The SC-400S, so far, only appears in Tom Clancy's Splinter Cell: Blacklist.
