Dead Neighbors

Dead Neighbors is a straight-forward 3rd person shooter (over the shoulder)where you must survive for 11 nights in  a city full of monsters. Snag pickups, choose upgrades when you have enough XP and deal with new threats every night. You'll have some breathing room during the day when new horrors don't spawn so spend that time wisely.

Pickups can be anywhere so search every alleyway. Most monsters can be given the slip if you're fast enough so use this to your advantage or stay on top of ammo. Even if you manage to find a nice, safe place, keep in mind you need to collect food to keep going.

Don't forget the zombie mode but it only has one diffiulty: nightmare 

The Halloween livestream linked above plays Dead Neighbors at the last few hours.

Download instructions: Just run the app called ArcadeShooter. Also I like to leave a previous stable build in case there's a game-breaking bug in the newest version.
