A very basic map likely made by someone new to creating maps.
It'll take just a few minutes to run through the map (you can only go one way with zero chance of getting "lost").
Finally is on a street with the bad guys coming from two directions. No way they will be able to get close.
Just keep shooting and when low pick up a fresh gun. Vehicle shows up you drive off.
Note that this is very similar to Exhausted Dead Life (1).
Would have been better to just built on the original version.
I still think both maps are by someone new.
