I'm currently working on a Nipah Virus guide for mega-brutal. I've already achieved a 3 biohazard score but I can't consistently win with the strategy I'm using. I decided not to post anything yet since this strategy has a very very low success rate. In 20 games that I've repeatedly used the strategy, only 2 games have won. I'm holding off on posting a guide for this scenario until I have a strategy that wins atleast twice every five games.In the meantime, achievement guides will be posted if I'm unable to post a guide by the end of the day(GMT+8). I know that everyone wants to have the guides posted as soon as possible, but please understand that I'm the only one working on it, at the moment. Please be patient, I'll post guides as soon as I possibly can.
