If the game freezes, just click inside it (games can get unresponsive if you click elsewhere on the page).
You’re stranded by the street lamp and zombies are all around you – truly it’s yet another zombie defense game. But, made in Unity3D which means – smoother, nicer and overall better experience for any player. Stand your ground, take all those undead down and buy weapons as you go. Collect drops to get more money and ammo. Good luck!
