Wave 12 only stopped me once I assigned two survivors to nonstop barricade repairs—FlashGamesBox runs it smooth enough to keep juggling menus mid-fight.
Headshots on sprinters are easier if you leave the rifle on single fire and tap `R` between bursts; panic spraying just empties the mag.
I always send my first survivor to scout—finding the shotgun by day three keeps armored zombies from chewing through the fence.
Remember to toggle fire mode with `F`; burst fire absolutely melts the brute that shows up every fifth wave.
Muting with `M` helps me focus on timing reloads, but I unmute before elites spawn because their growls are the best warning.
FlashGamesBox cloud saves let me bounce between laptop and desktop without losing my survivor roster—love that convenience.
Pro tip: keep one survivor idle so you can reassign them to turret duty mid-wave when the right lane gets overwhelmed.
Daytime searches feel RNG-heavy, but I never skip them—the medkit stash I found saved my run on the FlashGamesBox hard difficulty.
Turning mouse sensitivity down just for Dead Zed keeps my tracking steady when those leapers zigzag toward the fence.
