pandemic2.swf (application/x-shockwave-flash Object).
Pandemic II is a fairly straightforward free flash game where you “evolve” a virus/bacteria/parasite in order to infect the world and destroy humanity.
Humanity can be pretty crafty (even in flash games that humans write), so it’s a bit harder than it looks. I’ve played through it a couple times and can guarantee, at the lest, it will kill some of your time.
In a good way.
