As i am writing this, the game is still in early access. There are still missing features, most notably the Necroa Virus type, Tutorials & Scenarios. But allready the game is highly playable and damn addicting.
You are a plague, you infect people and evolve and the aim is to infect and kill everyone on earth in the end. There is strategy involved in picking the right mutations for your plague, keeping a low profile, not killing too many before you are discovered and later killing them fast enough before they can develop a cure for you.
There are several different plague types, Bacteria, Virus, Prion and more. They require different ways to evolve them to be sucessfull. The Neurax Worm which was added with the last patch was the most fun for me. The hunting for achievements was fun as well, altough alot of them arent implemented yet.
The game originally was made for mobiles and is now ported to the PC. It feels pretty good and polished for a port.
If i had one negative thing to say about the game then its about the bubble clicking, which gets tiresome and annoying after a while. Also it feels a bit too pricey, ~10 Euros would have been a much fairer pricepoint in my opinion.
You can get a mobid kind of satisfaction out of beeing sucessfull in this game, knowing that you just wiped out a whole planet. I just couldnt resist getting it, and overall i am sure i got my moneys worth out of it.
As long as you dont expect deep strategy you will have a good time with this game.
Its a nice timewaster with suprising complexity below its shell.
