Pros: Multiple weapon choices for combat, Ally kills add to your exp.
+/-: can walk, skill points, no durability to items.
Cons: Can't heal while doing a mission (exiting vehicle or going into building.), If an enemy gets too close you are fucked (unless it's just one enemy), Range for weapons isn't accurate, gun combat is weird, some enemies are too overpowered (like the licker and butcher), ally's die too fast, Missions give you the most items as defending the car is just a wave defense with barely any materials, Some guns shoot too slow, Surprise attacks from windows and doors barely give you time to react and seemingly happen at random and since shooting can only go sideways it will be hard to survive.
Overall: Game could use more work and programming; game is very unbalanced in certain ways.
