SMGs

Submachine guns, or SMGs for short, are pistol-caliber (9mm) automatic weapons with high rate of fire, but typically have low accuracy and damage per bullet. There are six SMGs in surviv.io: the MP5, MAC-10, UMP9, M1A1 CZ-3A1 and the Vector.

SMGs can be very good in early and mid-game, as they all use 9mm (Yellow) ammo, which is very common, and have a high rate of fire. However, in late game, it is advisable to replace them with an assault rifle or similar gun, as other guns typically have longer ranges, better accuracy, and do more damage. Despite this, some SMGs may be very devastating and powerful if used correctly, such as the MAC-10 and UMP9.
