It started with making the pre-conceptualized Unity file, which gameplay of it can be found at the bottom of this page. Due to there being bugs or issues with the gameplay initially, it sort of got me thinking of zombies (down the line) because most zombie games have a sound mechanic and since the NPC (roaming around) rarely attacked me, I thought "how can I make this a workable thing for the final build of the game?" Then it dawned on me of doing zombie apocalypse. Unfortunately, the CoVid-19 situation became a daily life-altering thing in the world, so there goes the plan of a final build but I drew up preliminary sketches of the possible NPC zombies, playable characters, environment, and collectibles. Later, I did colorized versions of the aforementioned sketches. Finally, I wrote up a Game Document that shows a possible game title and storyline/narrative. It then goes into detail of the key features such as the player choosing the character they wanted to play as and the collectibles having different results to the other like pick-ups (i.e. a smaller medkit giving less health back compared to a larger one).
