Mutant Zombie Monsters


You've been dead a long time, until now.

Hundred's of years ago, you lived as one of Fairview's founding fathers. Back then it was a prosperous city that anyone would be proud to be a citizen of. After a great and fullfilling life, you were buried in the beautiful Fairview Cemetary located in the rolling hills just outside of town. Since your death, many industrial companies have taken over the city and now something has gone terribly wrong. Toxic waste from a major company, Psylo-tek, has caused the undead to awaken and mutate into grotesque and dangerous monsters. After rising from the dead yourself, you realize that you do not have the blood-thirsty desire to kill like the other zombies do and actually have a shred of humanity left in your bones. As a skeleton back from the dead armed with a supply of scythes and a semi-automatic rifle, you set out to stop the undead uprising in Fairview and those who let this happen to the once beautiful city will pay.

Technical Information: 

Mutant Zombie Monsters is written purely in Javascript and is displayed using an HTML5 canvas element. This was my first game using the Impact JS game engine and was quite a learning process. I kept the sprites small so that I did not have to spend too much time on the artwork since I wanted to keep working on the code.

Mutant Zombie Monsters is about one thing: killing zombies as fast as you can without dying. Mutant Zombie Monsters saves two high scores for each level; the highest score based on killing zombies as well as the fastest time, which simply times how fast you can make it through a level in an all-out race to the end. Your fastest time score does not factor in what you kill or how many times you were hurt or died. Scoring bonuses are awarded for stringing attacks together to hurt or kill large amounts of zombies in a short period of time. You may watch your score bonus increase and become brighter if you manage to keep up the zombie destruction. If your high score or fastest time for that level is above-average, you will receive a two star or three star rating for that level. To master the game, get 3 star ratings for every level!

Scoring Bonuses:

  • Successfully Attacking any Enemy: +10
  • Obtaining a Health or Ammo Item: +100
  • Stringing Attacks Together: +10 PER ATTACK BONUS
  • Ten Attacks in a Row: +100 PER ATTACK RAMPAGE BONUS!
  • Twenty Attacks in a Row: +200 PER ATTACK FRENZY BONUS!

Scoring Penalties:

  • Receiving Damage from an Enemy: -10
  • Being killed by an Enemy: -25% of Current Points
  • Time Deduction for Level: -Your Level Time When Finishing Level
