Lovers in a dangerous space-time

Unravel (requires ea origin launcher)

Nobody Saves the world is 50% off and is really really great, a goty 2022 contender in some circles.

Battleblock Theater is an oldie but a goodie and 80% off.

And the obligatory It Takes Two plug, also a GOTY contender.

Future games:

Surmount is coming out this year and has a demo out: https://store.steampowered.com/app/1675000/Surmount/

I believe Moving Out 2 was announced

Howdy, I got some input. My partner and both play on steamdecks.

Saw this in one of the comments below but:

Lovers in a Dangerous Space Time

• Is a blast and I e of the few games you need another person to play with. The more the merrier.

Heave Ho

• Solid party fun.

Laura Croft and The Guardian of Light

• It's a $1.49 during the summer sale. Played this a while back. Phenomenal time.

PS: It says unsupported but I just booted it up and it loaded just fine, just tap the screen or use the track pads to get past the setting screen that loads up. Local co-op works and you can invite a friend.

Pico Park

• Simple game but get great for groups

Unrailed

• Recently had an underwater update and it's been a jive to play. Vibrant colors. Voxel art style, everyone gets into a rhythm. Played with 4 people last week. Deck friendly fun.

Nidhogg / Spiderheck /stick fight / Starwhal /duck game

• Different flavors of the same kind of couch co-op mahem

Plate Up

• New spin on the restaurant, cooking genre

Shovel Knight

• GEM!

Splunky 1&2

• Just tried this game. So far so good.

Ultimate Chicken Fight

• If you like Battle Block Theatre

Wildermyth

• Procedurally generated RPG with paper cutout art style. Play this with a couple friends had a good time.

Shift Happens

• It's a partner platformer

! If you get into Emudeck, Netplay is a thing, so is Parsec, but local play for console games works so well on the Deck!

Trine 2

• Played it on my nividia shield. It should work on the deck.

Tetris

• The new versions is a strangely addicting party game.

Lego Star Wars games might be a good choice

I’ve been having a blast with Earth Defense Force 5, and I believe it has split screen co-op.
