Kriss Vector

The Kriss Vector used to be the Security Department's main weapon. However, it is completely different than any other previous weapon Security can access. The Kriss has much lower damage but substantially better rate of fire (the firerate compensates for damage loss) and great accuracy. Vector's playstyle, due to its interesting characteristics, is quite a bit different than MP7's playstyle or any others' playstyles in Security Department Primaries tree.

This is the only gun in SD primaries tree which is usable at all ranges. But watch your trigger finger, because Kriss's firerate will eat the whole mag in 2 seconds.

Tips:

The Vector has an ability that not even a maxed MTF can lay claim to- it's tan, so you can pretend to be cool like MTF Commanders and RRT.

More seriously, the combination of Vector and Uzi is deadly indeed. Deadly enough actually to be on par with RRT. (Which in a happy coincidence, RRT also uses the Uzi.) Any single target that picks a fight with you will quickly learn what having their chest filled with lead feels like. Vector's one weakness, though, is that it cannot sustain fire for very long at all. Even firing the Uzi during the Vector's lengthy reload doesn't fix it, as there is a point where both of Security's weapons are completely out of ammo.

Furthermore, the Vector struggles at handling any SCP. It is a gun meant to kill humans and humans alone, and at that, it excels. But even 966 can take ages to put down, doubly so if you're alone.

For proper usage, treat the Vector like an upgraded Auto-Glock: Perfect in short bursts against single targets, with a fire rate that is comparable to the minigun, but lousy with crowd control and SCPs.
