The next game to join the US Instant Game Collection will be Irrational Games' BioShock Infinite for PS3.
The first-person shooter will become free to US PlayStation Plus subscribers as part of this week's PlayStation Store update on Tuesday.
In our BioShock Infinite review we said the game's "sky-high with character, conspiracy, controversy and chaos".
Although we said it doesn't innovate as much as we'd expected, we think it's still a "great all-round" game with "razor-sharp shooting".
Also as part of this week's PS Store update, Sony will offer discounts on more than 20 titles across PlayStation 3 and PS Vita for US PlayStation Store shoppers.
Last week's US PS Store update added indie game Don't Starve for PS4 and Ninja Theory's reboot DMC: Devil May Cry for PS3 to the US Instant Game Collection.
