Quote: "So you know the game idea is simple an online game, buy a gun, (different ones available) and shoot zombies with an online scoreboard to keep scores for playtime, kills, ect, i figure this is an easier start than planning missions and allsorts, (and simple is always best to start with)."
Zombie Shooter designs are popular, but, I rarely see any that take advantage of the viral nature of a zomb
ism. I would recommend using Arcade style game mechanics to achieve a high-action Zombie Shooter without requiring elaborate level/missions.
For example, In my Zombie FPS, Corpse Corps (which currently only exists on paper) you're a soldier task with job of locating the uninfected and guiding them to safe houses. Use your thermo-HUD navigation to locate the uninfected and safe houses, which change location during game play. Blast your way thru hordes of Zombies and score points and power ups at safe houses. Zombies can infect the uninfected thru prolonged contact and thus, multiply in numbers.
Doesnt seem like much, but with some variance in the environment you could squeeze out a lot of game play. Change the size and distance of safe houses, number and density of uninfected groups, number and type of rounds, speed of infection, visibility, use zombies for barriers to influence navigation decisions, and much more.
