The zombie mission is a great possibility to earn much money in short time. But it is boring.
-the zombies are all in one place
-they don'T move until they get shot
-it's in my opinion too easy to kill them
I think they should be everywhere in area 51. Like some years ago, the appear from everywhere, so you always have to run and to shoot and be careful not to be killed from behind. That was really fun. Now, you can sit with the sniper rifle in some distance and shoot them in the head and they die. That's as funny as watching paint dry.
Please bring back the zombies inside and everywhere in the area, it would be a great thing having as much fun shooting them like when they didn't just stand still in one place
