While me and my friend were playing Killing Floors we were talking about other good games we've played/wanted to play (Left 4 Dead, FEAR 2, Fatal Frame), I started thinking of what would be a really good game idea. This is what I thought up...
It's a Multiplayer FPS Zombie Survival Horror Game where you and others are in defensive spots trying to fight off zombies. Here's the catch, there are defensive spots all throughout the map, and if (lets say) 10 people are in the lobby when the game starts then 2 would start at 1 spot, 3 would start at another, and so-on. Your objective is to find out where the Military is picking up survivors, and on what by any means (Working radios, working phones, or flyers but the flyers culd be old ones and that spot is over run). During the day you head out and try to find other survivors, weapons, working radios/phone, or anything that may help. During the night you try to survive, but not every night the zombies will attack you. This game will also focus on horror and scary moments. It won't be like Left 4 Dead where it was fun to kill zombies with friends and no one was scared. It will be as scary as a horror game can get: Darkness everywhere at night, flashlights lighting up just a small part of a room, and everything else you can think of. Great attention to detail will be a must!
That's basically how the game would be played. Here's a little more details on it.
-Location
There will be multiple maps based on real life locations with newer maps being made by the developers after the games release. Players can customize their own maps. Maps will be pretty large compared to most other games so survivors aren't bumping into each others on the first day everytime, and so pick up spots can be sprend across the map but still not too close to one defensive spot. All, or most, buildings can be entered by both player and zombie, and nearly every building will have something useful in it.
-Daytime
This is your chance you repair your defences, find weapons, find survivors, and try to find out where the Military is picking up survivors. There will be some zombies out, but not as many as there would be at night. Daytime will last for 5-10 minutes (Still working on details), so decide what you will do that day before hand.
-Night Time
This is when the zombies will be out in mass. Your main goal is to just survive, but you can leave your defensive spot to look for equipment. The zombies may or may not attack you depending on the situation. Night Time will last 5-10 minutes (Again, still working on details)
-The Survivors
Players can fully customize their character to their prefrences, from gender to size, from clothes to facial look. (not sure about this next part yet) Players can also check a box to make their character look like a "Fresh Survivor" (clean clothes, clean face), "Tested Survivor" (Little messy, dirty face), or "Experienced Survivor" (Torn clothes, dirty face, blood stains). The placement of who will start with who and where will be completly random, but players can check mark other player names that they would like to start with. To keep player not amoung one group from communicating with another group over VOIP the game would have range chat always on. Like AHII's range chat, you can only talk to people who are within range of you. Player can talk to other groups if both groups have a working radio and know the other groups radio transmission.
-Weapons
There will be alot of weapons to chose from, but you will have to find them first. Everyone starts off with a knife of some kind (and maybe a pistol with very few rounds). Other weapons that will be found vary from assault rifles from abandoned military vehicles, SMG's, Shotguns (what would a zombie game be without shotguns

), Pistols, and just about anything else that could be used as a weapon (bats, axes, clubs etc). If you do happen to find a firearm you won't get a ton of ammo too. Most firearms will either have 1-3 clips once you find it (finding 3 clips with 1 gun is rare though), but you can search around for more ammo.
-Zombies
The Zombies would be like any other zombie we've seen in every movie/game, fight among each others, wander around a bit, kinda stupid too. However, if the zombies notice a survivor they will attack in great hordes. They won't be very hard to kill (harder to kill than a normal human though), but the vast amount of them attacking will overwhelm anyone caught alone.
-Defensive hold outs
Where you spawn to hold out will vary from others, but they will all have just about the same feel. Boarded up windows, tables and chairs blocking doors. You will also sometimes get a weapon in your hold out if your lucky (spawn in gun stores manager room

).
-The Enviorment
Just about everything on the map can be communicated with. Open every door in every accessable building, open cars to look for supplies, just everything. (Maybe even run down some zombies with a car that still has gas in it, or use that car to get to the pick up point

)
-Weather?? (Not sure about this, it might not work)
As each day passes, weather will change (after all that's how it is in real life!). Some days it will be rainy in which visability will be limited. Some days it will be foggy limiting how far you see from down the street to just a few feet in front of you(This would make it very frightening if zombies attacked

). Weather will also change throughout the day. it would be foggy in the morning, but clear up later on.
