No bugs were found asides from bots having trouble with ladders (as they always do). The title serves its premise and nothing else. You fight from building to building and occasionally meeting witches in the way. Areas are very open which gives you enough room to maneuver (it also gives the infected a chance to surround everyone so stay close). Infected spawn sparingly and are easy to dispatch.

Quite a few things to note:

• Weapon and ammo spawns (not throwables) are sparse. You'll see more medkits and laser sights than an ammo pile. No T2 weapons (nor any sniper rifles for that matter) until the finale. Laser sights in particular are quite useless in this environment as we're battling in close quarters most of the time.
  
• Layout is so-so. It's a hybrid of No Mercy and Dead Air. It being good or bad is up to you.
  
• The sewers should've only been on one map. A crescendo event occurring in the sewers was reasonably a bad idea especially given that it's dark and has barely any sense of direction (don't go in the water unless you want a headache). Or at least give us items like ammo, kits, and guns before and after the event.
  
• Environment detail was... okay, I suppose. I won't dwell on that deeper for this is your first campaign.
  
• The finale could use a little bit of enlarging. Those barrels are a recipe for death, especially if it seems like they all explode one by one should a barrel detonates. Having them uncomfortably close to the gas cans is a bad idea as well.

Other than that, fun map. An impressive feat, too. Keep it up!
