Infectonator takes a retro-perspective on the usual zombie domination games. However, it requires much more intelligence than many would first realize. You are assigned a number of people to kill, and utilizing the upgrades available to you through the collection of coins you have racked up, you must infect the petrified humans in only one click of the mouse...

The game poses no difficulties with its controls, simply an understanding of how to succeed is all that is needed. This is introduced to you at the beginning (tutorial) level, even if you are starting again due to the dreaded 'gameover'. On each level a swarm of people will mindlessly walk around the screen, you must click the mouse to designate a certain area of people to become zombies. Therefore you must make sure that you choose the right time, only creating one zombie is going to be bordering on impossible, however if you change a large cluster of people as they happen to pass each other then a larger amount of zombies will be made.

On the completion of each level you are given the opportunity to purchase upgrades and bonuses.

The upgrades consist of:

Lifespan
Speed
Damage Resistance (your zombies will be attacked as well)
Attack
Infection Chance
And the bonuses:
Increase virus speed
Money collecting radius (how far away your zombies have to be to collect the gold coins)
Bomb (used by the same method as infecting)
Ability for virus to penetrate through walls
Each skill can be upgraded 10 times, when you scroll through each upgrade it will display at the bottom what the upgrade will do. For example if I have just started, my speed will be 30, if I upgrade all 10 times I will reach the maximum speed for that skill which would be 120. Four times more agile than your initial speed.
Bonuses on the other hand have a large price to begin with, with the one exception of the 'Ability for virus to penetrate through walls', the others can also be upgraded, however not as much as 10 times. The price however is very steep, yet their abilities can prove to be priceless.
