Played once, would not play again.
Pros
A lot of time went into this.
Good idea for the ending.
Cons
A bland map which can't be hidden by making it dark. It would have been better to make the areas smaller and better than long and boring.
Poor choice of weapons.
No special ammo drops or lasers that we could see.
No melee weapons.
Lots of glitches with objects zed spawns and structures.
Re-use of the same structures makes it uninteresting.
Pathing poor.
Lots of rooms without windows.
Lots of doors you can't open. Make the insides of more of the buildings or shorten the map. The odd locked door is okay.
Bland map with an incomplete feel
