The TEK Z-10 is basically an upgraded version of the T3K Urban SMG from Saints Row 2. At its base level, it’s your standard submachine gun - but by the time it is fully upgraded, it’s arguably the best weapon in the game. As you progress through the upgrade path for the TEK Z-10 you will receive things such as a larger ammo magazine, a red dot sight and a silencer for better accuracy and reduced recoil, and a side-mounted laser sight attachment for better accuracy while firing from the hip."

"With the TEK Z-10, you will eventually feel as if nothing can get in your way - not even a group of 15+ Luchadores coming at you, armed to the teeth. This is because the fully upgraded TEK Z-10 fires extremely powerful incendiary rounds that catch your enemy on fire with a single shot. They will stop attacking you and worry about themselves, going into a ‘HOLY ****! - I’M ON FIRE!’ animation."
