Their are six stages all representing parts of the body you are infecting and after completing any one of them you unlock the special ability that comes with that stage. Each of these stages are quite unique and have special enemies and environmental effects; For example the stomach has a continually rising ocean of acid that you must keep ahead of and the intestines are dark and you can only see a short distance. Additionally, these stages are procedurally generated, making them different every time you attempt them.
It is also worth noting, unlike Hydorah, this game is playable and even beatable (more of less) by people who are not particularly experienced in the shooter genre.
So for anyone who is interested they can check out Viriax here.
