The Resistance 3 beta has today started with certain PlayStation 3 owners being able to check the multiplayer section out early.
While certain PlayStation 3 owners will be able to get into the beta, if you purchased SOCOM 4 there is a code in the game box which will allow you to get into the beta.
The Resistance 3 beta is a considerable 1527MB download for those who plan on playing, which is roughly the size of a large demo.
