Game Overview
Game Concept Introduction
Zombocalypse is a 2D side-scrolling action game with RPG elements, placing the player
in the advent of the zombie apocalypse.
You are Jon Fulton, a spec ops soldier on a reconnaissance mission of riots breaking out
in a large mountain enclosed city, Fairfield. Your chopper crashers, and you awaken surrounded
by zombies and with your team nowhere to be found. Your sole mission is to survive for as long
as possible.
The player must run back and forth in an area collecting weapon crates and defending
themselves from an onslaught of undead to achieve the highest kill count until they are
eventually overwhelmed (score based gameplay). As players progress through Zombocalypse,
your character will gain experience and rank up, unlocking Call of Duty style Kill Streaks, perks,
weapons, new areas, and character customizations. The story is revealed through intricate and
stunningly illustrated cut scenes.
Genre
Action-Arcade / Shooter
Target Audience
Zombocalypse is focused on teenagers 10 years old and up. Simple gameplay and cute graphics
appeal to both male and females.
Technical Specs
Platform: Flash browser based game Language: Actionscript 3
Dimensions: Width: 720 x Height: 480
FPS: 30

Game Flow Summary
The player starts in main hub. Can edit Perk or Kill Combo load out. Then players chooses an
area on the map. Player will move left and right in a small area, using the default machete
weapon or picking up weapon crates to fight off hordes of zombies that increase in number and
strength the longer the player lasts. Game continues until the player is overwhelmed by zombies
and dies. The game over and results screen will then pop up. The player will receive experience
points based on their performance. Player can then choose to replay the level, or choose a new
one. If a certain score is reached, a new area is unlocked.
7
Look and Feel
All characters will be cartoony (similar to the style of Castle Crashers) with big heads, but a
smaller body with short legs and arms. Zombocalypse will be a game that takes itself seriously
although delivering a cartoony style. Soft color pallet with solid color outlines. The main
character will look tough and robust. The overall feel will be slick and polished looking with
subtle grungy accents and hard outlines. Shades of red and grey are the main color schemes.
Minimalism and simplicity encouraged as much as possible.
Themes of inspiration:
- Left 4 Dead games theme and UI
- Dead rising main menu and UI
8
Game Mechanics
Gameplay is fast paced and strategic as the player sweeps back and forth across the screen to
pick up crates, call in ally support, and rack up kills until the player is eventually overrun by
zombies. The game is simple to play, but hard to master: each weapon has its strengths and
weaknesses, the different zombie types present challenges, crates must be timed, and Kill
Combos must be strategically used. Players ultimate goal is to get the highest online score.
Game Progression
The player continuously plays a level until they die, gaining experience through each play
through or "round". Reaching a certain score will unlock the next area. Each area has a bronze,
silver, or gold medal award based on your score.
Objectives
Zombocalypse 2's game play is score based. The main objective is to get the highest score
possible. Other sub-objectives:

Reach highest rank

Unlock all achievements

Unlock all perks, weapons, areas, and characters

In the early levels, novice players will be able to rank up easily, gaining multiple levels per
round. Mid game, an average player will be able to rank up at least once per every round. Later
levels will require players to master the game to gain more experience and rank up faster. Things
are unlocked often, giving constant incentives for players to continue playing and to create a
sense of progression.

Currency System (Coins)

The currency standard is the Coin.
Sometimes coins are dropped after a zombie is killed, which must then be picked up by the
player. Coins are used to buy weapon upgrades (500 C, 1000 C, 2000 C respectively) Each
zombie drops a certain amount of coins.
There are 4 types of coin drops (icon descriptions below):
1. One coin = +5 coins
2. A stack of coins = +10 coins
3. One Coin Bag = +20 coins
4. One Gold Bar = +50 coins

Global Game Elements
Storyline
Jon Fulton and his Bravo Spec Ops Team are briefed on mass riots breaking out in
Fairfield, a sprawling metropolis enclosed by mountains. Alpha Team was first sent in to
investigate but quickly lost contact with HQ after entering the city.
Jon and Bravo Team are sent on a highly classified surveillance mission to find out what
exactly is going on. However their chopper goes down abruptly as they pass over Fairfield,
crashing in a park clearing. John emerges from the wreckage but is attacked by rioters before he
could find his squad mates.
Jon quickly realizes the rioters appear to be grisly, corpse looking, and heavily mutated.
He defends his position and calls in support, but knows he can't be evacuated due to the high
classification of his mission. Jon decides the best place of refuge would be the nearby Military
Base. He is able to clear the park briefly, making his way Downtown.
Jon finds a group of survivors holding out in a small building on the outskirts of the city.
Hordes begin to attack the building, and they hold out for as long as they can until they are
eventually overrun. Jon manages to escape, and is forced to fight alone through Downtown to the
main highway.
Jon travels down highway towards the Military Base. However the base is completely
overrun, with the main facilities smoking and on fire. He fights his way towards one of the
hangars, and finds remnants of his lost squad mates gear. Jon fights for as long as he can on the
military base, and just when he is about to be overrun he finds a hangar with an entrance into the
mountain. He heads in, hoping to find not only refuge, but answers.
