UNNAMED MULTIPLAYER ZOMBIE SANDBOX GAME
Still in development, also, you need the byond engine, which, as far as I can tell, includes a bunch of worthless anime games, and the superb Space Station 13. I chose to make it in byond mostly because multiplayer programming is beyond my understanding.
Here is a link to BYOND if you choose to try this game.
http://www.byond.com/ I don't think you need to even register, (But I could be wrong). When you start BYOND go to FILE at the top, then open location. Once there enter byond://67.167.142.18:64826 I will be running the server tonight for a while, and possibly tomorrow.
Currently, the game is just one small city, (Roughly 20 buildings?) But there are a good amount of features. Movable furniture (For barricading.), Zombies flood into windows. (Door are not damaged by zombies currently), Set clothes/gas pumps/etc.. on fire, raid supermarkets/hardware stores/houses/gas stations/clothing stores/ etc....., Craft things using grills,sewing machines,and other various machines/components.(You can also drag these machines, as they're too heavy to pick up, to a barricaded house to build up the ultimate hideout full of home-ey amenities), and a couple others I forgot.
The hunger and thirst systems are not in effect yet. In their absence food heals you.
This is not the final product here, so, don't judge TOO harshly, but if you like it, lemme know.
FUTURE FEATURES:
Morale - Can be raised with drugs/good food/music/etc.
Vehicles
A MASSIVE CITY
