This week's PlayStation Store additions are marked by Klei Entertainment's Don't Starve, which is now available on PS4. The roguelike survival game from the makers of Mark of the Ninja is $14.99, but also happens to be one of two games that are free for PlayStation Plus members starting this week. The other PS Plus freebie is DmC: Devil May Cry for PS3.

Two games joined DmC on the PS3's digital storefront this week: Tiny Brains ($19.99) and Twisted Lands: Shadow Town ($11.99). Tiny Brains already launched on PS4, and the game is Cross-Buy-compatible for those with multiple Sony consoles in their household. StreetKix: Freestyle is also available on PSP for $11.99, discounted to $10.79 for PS Plus members.

Among PSN's new add-ons is the Illustrious Pirates Pack for both PS3 and PS4 versions of Assassin's Creed 4, which is $9.99 and free for season pass holders. This week also saw a handful of permanent pricing changes on PSN, including Saints Row 4 ($39.99), Need for Speed: Most Wanted ($19.99), Tiger Woods PGA Tour 14 ($39.99) and the Artorias of the Abyss DLC for Dark Souls ($9.99).
