With the Winter Holidays coming up, here are some games you may wish to spend playing indoors on those cold days. Sony has just announced their line-up for PlayStation Plus Free Games December 2018 which will be available on Tuesday, December 4.

On the PlayStation 4, there’s Soma, a sci-fi survival horror taking place in a remote underwater research facility, where machines seem to be developing their own personalities. And Onrush, a vehicular combat game where players use off-road vehicles such as buggies and motorcycles to take down opponents and win.

For the PlayStation 3, there’s Steredenn, a space shooter where players must survive against space pirates in chaotic combat. And Steins;Gate, a visual novel involving students who use technology to alter the past.

And on the PlayStation Vita, there’s Iconoclasts, a 2D action platformer with gameplay similar to the classic Metroid, battling enemies and solving environmental puzzles as the player-character Robin fights against tyranny. Iconoclasts is also a cross-plat on the PS4. And there’s Papers, Please, a puzzle simulation game where players are a boarder crossing immigration officer in the fictional dystopian country named Arstotzka.

Among the PlayStation Plus Free Games December 2018, only Onrush and Steins;Gate have Platinum trophies. Steins;Gate is certainly the easiest, being a visual novel, requiring only 5 hours if using a guide and text-skipping. While the Platinum for Onrush is of average difficulty depending on your skills, requiring anywhere between 15-20 hours of gameplay.

Also, unlocking 100% of the trophies on Papers, Please is reasonably easy with a guide and only requiring about 3 hours, while Soma is not hard and needs only about 8 hours.
