Well-known drive-and-slaugher Zombie game Gunner Z, which has been getting progressively better since its initial release, has received a huge update that brings its version number to 1.50. The update features upwards of 30 new missions in the "City Outskirts" area, 28 new monsters to take out, and many other exciting new features.
On top of the new missions and monsters, version 1.50 of Gunner Z comes with a new VR1 Bandit truck, 2 new weapons, 2 new P.E.T.S. models, as well as new achievements, leaderboards, and challenges. To top off this expansive update you'll be getting the usual "bug fixes and improvements," too.
