A few days ago, Capcom has confirmed that, in addition to the three campaigns of Resident Evil 6 dedicated to Leon, Chris and Jake, the game will contain a fourth unlockable after completing the other, dedicated to Ada Wong. Today we discover even the existence of a fifth campaign, called "Prologue", which however do not know the length (but saw the title we expect both rather short), or whether it will be playable before the three main campaigns or even if it will unlock at a later time.

In the selection menu title campaign, however, appears to last; I'll show you later, waiting for more information from Capcom.
