Neighborhorde

- I did this one with 1 friend on the Playground Map

- At least when on the last wave, continuously run in a circle around the map picking up items and shooting enemies until all enemies die off

- If you can manage to go the whole attempt without getting Snowmen then that is ideal and you should take advantage of that situation! I HATE SNOWMEN

- Skip to 13:04 for the Final Showdown

Favorite Weapons:
- Bottle Rockets (Very Strong)
- Narf Gun
- Marshmallow Gun
- Bubblegum Machine (Powerful, but you run slow)
- Boombox (Attracts enemies)

Favorite Power-Ups:
- Cellphon3z (Bigger Friendzone)
- Daylight (Huge Friendzone in Daytime)
- B-Day (Presents drop when out of ammo)
- (Presents drop in Friendzone)
- BFFs (Friendzone heals faster)
- Picky (Choose out of 4 weapons instead of 3)
- Magnetic (Pulls gifts and items into Friendzone)

Ok so this achievement is hard but do-able solo. I used the first map because you can use alot of the buildings for cover when your useless a.i buddies get downed which will be ALOT. You will need to get quick revive, extra health, bigger friends circle are a must. Then try and get the stereo it will help alot on boss levels as enemies are drawn towards them which gives you a chance to re-vive team mates. The heal when out on ammo perk is good as well because when you are over run just keep dashing with the a button in circles around the map. This will take a few attempts and alot of luck it was the last achievement I unlocked so stick with it. I expect if you have a few people for local its alot easier. Good luck
