Another week, another round of goodies of PlayStation Plus members on PSN. The biggest of this week's bonuses is a free download of Guardians of Middle Earth, a game that does a surprisingly good job of bringing the MOBA genre to consoles.

There will also be a handful of discounts on other games. Jordan Mechner's Karateka will see its price punched and kicked down to $5. Twin-stick shooter Big Sky Infinity will be $5.99 and features Cross Buy, unlocking the game on both PS3 and Vita. Finally, we have the stylish, humorous platform adventure Knytt Underground, which will be available for only $5.
