Are you even sure that there are cheats for that game. I don't know that much flash games that have cheats for it. I think you should ask for hints and stradegies for the game instead of cheats.
same as plokkey fire rate+shell size= ownage but u can quit on fire rate when u get 5 cuz it wont go much faster. ive gotten 10 shell size+5 fire rate. i owned so bad but then i got bored
There are no cheats for this game, and seriously, who need them
As many people have already said, 5 fire rate, 3-5 speed (that depends on your style) and the rest to shell size, you don't need anything else to survive but to be fast choosing your target and clever judging when saving a hostage is worth the risk or not.
Note that the faster you rescue the hostage, the more points you'll get, you'll be getting less as the bar drops and when it depletes, it becomes a freakin' lvl 1 zombie, not the big deal.
I followed the guide at the start. At the start immediately get ur dude upgraded to shot speed of 5 then after that put all your points into shot size. O and then just move around and shoot and collect hostages until u have a shot size of 5 then u can stand at the bottom right hand corner right next to the bottom right hand corner zombie entrance.
O and the leveling is glitched. After you get past 10000xp needed to get to the next level, the level bar becomes lik 2 9999xp bars. But after awhile it becomes one, but then it takes a long time for the 20000 - 10000xp to get done, then when it gets below 10000xp it goes down really quickly.
O and I got really bored after awhile but I got up to level 60 with 5 shot speed and 13 shot size. =P
