What is it?


Game Concept
The first concept take is a simple side scroller which will be developed using Unity or the engine the team comes to agreement on and will allow the team to get a release out quickly to make the actual game. A fps online with the ability to go in every directions. 
What’s the game about
The basic concept of the game is a run a gun, free roam zombie killing mayhem. four players start out in a the main part of the map; if the map is a baseball arena, the players will start out near the gates. The players do not have to pay for anything, just survive, getting highest score, the most time survived, or just plain getting the heck out of there. 
Rounds
There is no set time that a round will end, instead it is totally based on how great you are with that shotgun, or any other weapon you choose, and getting the set amount of kills. After the round ends the player is transported to a screen that has the player info and stats, the player from there can level up certain ability, use blueprints to obtain special items or weapons, get some kick ass customization done to your clothes or your weapon and get right back to the action. This little siesta will allow players to take a break from the game and get a drink, quick bathroom break, go outside, or defend themselves from zombie mayhem of their own. 
Items/Weapons
The item and weapon category will start out very miniscule. Items may only startout with basic clothing, but will later lead to being able to wear, kevlar, leather jackets, and other heavy apparel protecting you from the undead. Guns may only start out with two or three options, but as the game progresses, so does the complexity, and use of these weapons. The weapons range from a standard pistol, to a make shift bazooka, obtaining any of these weapons, will allow achievements to be unlocked and 
Achievements
Achievements the moment that everyone has waited for to be mentioned. This game allows so many easy and difficult achievements, hand crafted from the smartest minds, these achievements will keep you playing this never ending zombie mayhem, each level holding its on deep dark secrets and every weapon expecting to be customized, the player will have the most outrageous time trying to complete them all.
Map packs and Weapons Galore
Maps and Weapons will be constantly modified and added to the game, the game will not alway have set locations for weapons making it difficult for the player to complete master the game. Weapons will be added due to the great minds that are the players, playing the game, everyones opinion matters and will be taken into account. Maps will be constantly added as well, there may be only a mall and a baseball arena, but just you wait, there will be tons more in store for everyone to be amazed with.
Basically this game will be a shell to outside game developers to attach their ideas too. Once the shell has been created, game developers will be able to create maps, weapons, characters, anything and be able to submit it to this team and we will verify that it is practical and original and use it to bring more widespread approval to the game. 
Development platform, initially just PC and OSX. After the team has gotten everything on that worked out, it will be ported to iOS and Andriod. Continually the game will be brought into a new realm which is the FPS Online world.
