Hydorah developer Locamolito has just released its newest off-the-wall arcade title, Variax - for free.
The "medical terror arcade" game features short but sweet procedurally generated levels.
As the variax virus, your task is to infiltrate a human body and take down a last-defence nanobot mechanism installed in the brain.
Retro graphics and a chip tune soundtrack make destroying humanity as delightful as can be.
You can download the PC-only game plus an assortment of other goodies here.
Locamolito's sh'mup Hydorah was also released for free, and won acclaim on the indie scene in 2010.
Thanks, Game Set Watch.
