The limited ammunition available while in sentry mode is a reason against using it for long-term defense in most cases, on top of the fact that only one sentry gun may be deployed by a player at a time, with any older guns self-destructing when a new one is thrown. The sentry gun does tend to sweep the immediate area both when firing at a target and after it kills the target however, which is rather inefficient for ammo consumption. It is able to fire upon valid targets from incredible range so long as it has line of sight on the target, and despite the gun's persistently low damage output, it is compensated by its rate of fire and accuracy. Its secondary firing mode, where the Laptop Gun can be deployed as sentry gun turret, boasts incredible advantages over its regular configuration. It is handy for a quick response to threats, and ideally suited for defense-orientated players. The damage output is rather low, but can be compensated for by its volume of fire. In this game, the Laptop Gun is a sub machine gun that boasts a 50 round magazine and a dizzying fire rate (lower than the RC-P120, but higher than the CMP-150 or Callisto NTG). The gun runs on the remaining rounds in the magazine but it can put down a lot of hurt on those who remain in its sights. The secondary mode allows the user to deploy the weapon onto nearly any surface as a sentry gun, which helps lock down important areas. The more recent models come with a 2x scope, making target acquisition easier. But it takes awhile to deploy as a sentry gun due to its slow unfolding time. Its average fire rate of 1000 RPM makes it effective at suppressive fire.
