With the new Scorepocalypse spin-off from All Zombies Must Die, I have the problem that I am sometimes already at wave 50, but score is still around 100.000 only. Silver Medal is 400.000 Score.
From what I understand, Zombies with status effects ( sonic, fire, mutated etc. ) give the multiplier as long as they live and it drops when zombies with a special status die.
But in the same time, those special zombies are very fast and become a threat pretty quick.
So what is the best strategy to acummulate a high score and multiplier early on and are there any other factors that help?
