Resident Evil 5 · Machine gun
VZ61
The VZ61 has extensive capacity upgrades and a critical-hit track; fully upgrading it unlocks the Gatling Gun.
How it works
The item reference lists the VZ61 in Chapter 1-1 and shows upgrade tracks for firepower, reload speed, capacity, and critical hit. It calls this the first machine gun and says that fully upgrading it is required to unlock the Gatling Gun. Machine guns are described as automatic, with recoil limiting their effective range and rapid ammunition use.
When it helps
If the Gatling Gun unlock is a goal, the source states that the VZ61 must be fully upgraded.
The tradeoff
The source describes machine guns generally as limited in effective range by recoil and quick to use ammunition.
