One PS3 and two PS4 titles will be entering the Instant Game Collection this week, as part of PS Plus free games for June 2014.

This is a huge week for the PS Plus subscribers as three free games will be available once Sony's Instant Game Collection gets an update tomorrow, June 3. According to a post on PlayStation Lifestyle, the PS Plus free games arriving for PS4 owners will be "Trine 2: Complete Story" and a cross-buy title with PS Vita version, "Pixeljunk Shooter Ultimate."

As described on GameZone.com, Trine 2 is a "puzzle platformer set in a gorgeous fantasy world" while Pixeljunk Shooter Ultimate is "a twin stick shooter that involves blasting things, exploration and puzzle-solving."

Moreover, in time for the NBA finals, the basketball video game NBA 2K14 is also arriving for the PS3 owners tomorrow as one of the PS Plus free games.

These PS Plus free games are set to replace "Resogun," "LittleBigPlanet Karting," "Stick it to the Man," "PES 2014", and "Uncharted 3: Drake's Deception Single Player" from the Instant Game Collection. 

The other PS Plus free games slated to enter the Instant Game Collection later this June 2014 are:

Sly Cooper: Thieves in Time (PS3)

Mutant Mudds Deluxe (PS Vita)

Terraria (PS Vita)

Reportedly, June will also be the final month in which PS Plus free games will be released every week. Beginning in July, PS Plus subscribers will be able to get all the free games every first Tuesday of the month. These PS Plus free games will be available in the Instant Game Collection until the first Tuesday of the following month.

In addition to PS Plus free games coming this week, subscribers can also look forward to discounted games available starting tomorrow. For instance, add-ons for Rainbow Moon will be available for a cheaper price. Head over to this US PS Blog post to see the full list of items on sale.
