The controls are the same as the other versions except for one thing. If your score is 15 or higher, you can use the S key to activate Sanitizer Blast, a new attack for the doctor. Or you can save up 20 and press V to use Vaccine Summon. Press M when you have 50 or more to enter Machine Gun Mode There is also new enemies! The Evil Vaccine: If it catches you, you will lose a life. The Heart Covid will take 3 hits to defeat Sanitizer blast does not affect Vaccines and Evil Vaccines. In addition, All of the Covid enemies also got a new texture. Have fun!!!!!
