PlayStation Plus members get Super Street Fighter IV free this week

The PlayStation Network update for this week will add Super Street Fighter IV: Arcade Edition and Rochard to the Instant Game Collection for PlayStation Plus members.

The PS3 games add to the ever growing library which saw BioShock 2 added last week next to Infamous 2, courtesy of Joystiq.

Most people will be familiar with Super Street Fighter IV, where Rochard is described as "Fantastic puzzle-platforming in the form of taking control of astro-miner John Rochard." It goes on to exclaim, "You’ll be addicted to the gravity control mechanics of Rochard as you solve environmental puzzles and explore new ways to navigate the wonderful trappings of this galactic platformer."

The update takes effect between 2:00pm and 5:00pm PST, according to the PlayStation blog, which has more details on each game.
