Don't Starve & Binding of Isaac Secret Ponchosto join PlayStation Plus library on PS4

This month marks the beginning of PlayStation Plus Instant Game Collection for PS4. The first two free games are Resogun and Contrast. But what else is down the line? More indie games, obviously.

The Binding of Isaac: Rebirth, an updated version of the classic roguelike dungeon crawler, will be available for free to Plus members when it launches in 2014.

In addition, Klei Entertainment's quirky survival game Don't Starve will also be available free on Plus when it launches in "early January." According to Joystiq, the PS4 version will launch with all content from the PC version, and that both versions will update in parallel after release.

Top-down multiplayer shooter Secret Ponchos will also be available for free when it launches on PS4. We spoke to Switchblade Monkeys, who noted that having a large community of members at launch is more valuable than any payout Sony offers for making the game free on Plus. The company hopes to offer more characters after launch as a way of monetizing free players.

Other Plus games confirmed for PS4 include DriveClub and Outlast.
