The October 16 PlayStation Store update will bring more specials for PlayStation Plus members. In addition to the PlayStation All-Stars Battle Royale beta, members will also receive Payday: The Heist for free.
Payday: The Heist for PS3 may not have gotten updates to the extent that the PC version enjoys, but the core game is still a pretty good cooperative game.
PS Plus members will also get early access to The Unfinished Swan for $14.99. This game will be released to everyone on October 23.
There are also a few discounts to be had. Highlights from the list of discounted games and DLC include inFamous: Festival of Blood for $2.50, Dead Space 2 for $9.79, The House of the Dead Bundle for $15.39 and the Costume Quest Complete Bundle for $3.75.
