In addition to a robust single player mode, there's a dynamic multiplayer mode and in that multiplayer mode in Resistance, you can get infected with Chimeran virus. Now, that may sound a little intimidating initially, but it's actually a good thing because the Chimera virus actually gives you a multiplayer bonus experience. In fact, you can take it a step further through NEAR and infect your friends. Once you've infected them, they get that same bonus in multiplayer, so everyone's getting a little bit of the benefits.
