This game was made for the Newgrounds Halloween Competition. I've been working on this game for awhile now and its finally completed. You're able to select four different difficulty modes; each mode having a higher score multiplier in the end. WARNING: I advise you to play on medium or higher. Easy mode is a little laggy because of the machine gun turret! There are eight guns to unlock and use and two different types of zombies; regular and demon. The demon zombies appear every five rounds (unless your playing on Insane mode, which then it's every three rounds).
All the background ambient music tracks are custom made for the game by a friend, Isaac (U.2) The other sound effects are downloaded from www.freesound.org
Hope you have fun playing the game! -Sumo
EDIT: Thanks for everyone enjoying the game! I was able to get 1st prize in the competition because of all of you! Thanks!
