Needle tosses into headshots while the achievement strip lights up keep me grinning; clearing a wave to grab the next gadget feels perfect.
I bind Z/X to my mouse thumb and slam between the revolver and rail dart, then smash NEXT LEVEL the second the counter hits zero for a fresh weapon drop.
Finishing Rookie Trial in one sitting unlocked the mini-nuke; nothing beats vaporizing a pile of micro-zombies and watching three achievements pop at once.
The targeting is so crisp that I can juggle bodies midair with the throwing knives while the timer bleeds down toward the last shambler.
Time Slayer might sound grindy, but chaining 4 perfect clears fills the inventory with absurd toys - dart guns, ice beams, and that glorious tesla coil.
Mouse flicks plus left click spam keep combos alive; I love seeing the progress bar up top glow before the last crawler even stands up.

Achievements lining the HUD are a perfect guide - finish two for the Rookie badge, swap loadouts, and suddenly Time Slayer is within reach.
My favorite run is syringe + shotgun: pin a walker to the sign, swap, then blast the pile while the kill feed scrolls faster than I can read it.
Playing on FlashGamesBox means zero setup - load the page, hammer NEXT LEVEL, and chase whatever achievements the night throws at you.
