Infection 2 Bio War Simulation is the sequel to Infection, which is the popular kill-em-all disease-spreading simulator that takes a bit of influence from the original Plague Inc. Like the first Infection, you use DNA to purchase upgrades to your pathogens, but unlike the first Infection, there is now a premium currency in the form of gems. Read on to find out how to get more free gems and DNA in Infection 2 Bio War Simulation!
DNA is accumulated within the current round that you’re playing, and cannot be carried over from round to round, so unfortunately, you can’t count on doing that. You can, however, do a few things to speed up the earning of your DNA. The best thing to do is right at the beginning of a new game, avoid buying any transmissions, symptoms or resistances for awhile. Set the game to double speed and spend somewhere between 10 and 20 minutes (or more) simply popping yellow DNA bubbles and letting DNA collect on its own.
DNA collects on its own residually after a new country becomes infected, or after people start dying in a new country. Yellow DNA bubbles pop up at random times from any country that has already been infected. Red DNA bubbles pop up from a country that’s not infected as soon as it becomes infected, especially after a red plane or a red ship land in that country.
To maximize the efficiency of DNA gains, wait for a long time as stated in the second paragraph while the DNA collects. Then buy a list of transmissions and collect more. Then buy the rest of the transmission list after that slows down. Then finally, buy the symptoms (all at once if possible for maximum lethality). Fit the cures in different places. Buy them initially except for the ones which decrease the cure bar. Buy those later on.
To get free gems, first, wait for DNA to build up as with before. Then buy loads of transmissions and watch the infections pile up. Then around the time that the whole earth becomes infected, wait for a green pop up bubble to show up. Tap it and you will get one free gem. Do this during every round to load up on the free gems.
If you are impatient, you can always purchase gems. Gems will go on sale every so often, so wait until a daily deal or a limited time developer’s deal comes around to purchase them. Never purchase them at full price if at all possible.
