Raid: World War II, you might remember this game coming out? I don't. It certainly has a bland name (though you can't fault it for being unclear about what the game is lol) but suffice to say the story goes that on release this game flopped compared to similar co-op heist/raid shooters like it even though the development team was well situated to make a hit on paper.
The weird thing is, at some point since a small passionate team of developers were given more creative control, and all of a sudden diehard fans of Payday 2 and similar games are singing the praises of Raid: World War II, in 2025, which is a game released in 2017 on an already out of date engine..... Weird, but the reason that should matter to you is that the game is far cheaper than it should be for the quality and amount of content in the game and the only real drawback is the game is made on an engine clearly long in the tooth (I mean I love Xonotic so... it is all a matter of perspective I guess lol).
Also, it just feels especially relaxing right now to blast Nazis and steal their gold!
The tutorial is very quick, fun and doesn't require a big investment of focus or time, you get to the fun bits fast. This a great pick up and play game on the Deck to play with friends or by yourself.
I would describe the feel of this game to something like Warhammer Vermintide 2 but with guns (though I believe this game is literally made on the same engine as Payday 2, so that is a good comparison as well). There is a ridiculous amount of enemies and battles can be quite frantic (there are almost always mounted MGs placed in convenient places for you to use for example). There is also stealth mechanics/options too.
This game is a blast on the Steam Deck, though I guess it is worth noting that I play all kinds of shooters (PVE and PVP) on the Steam Deck using the onboard joysticks and gyro so your personal comfort playing with the onboard controls may vary.

On the other hand if you are looking for a PVP heist game that seems to have similarly fallen on its face (though it is much earlier in its development cycle, being in early access) despite actually being an awesome game underneath, check out Due Process which is currently a whopping $1. This seems like the kind of game that might go FTP, so you might end up being able to get it for free one day, but I think the amount of game on display here already is easily worth $1, especially because it combines common FPS PVP and PVE tropes in ways that R6 Siege seems to have largely failed to do as successfully. Watch some gameplay before judging it as a $1 shooter.
You forgot to mention John cleese is in the game.
Yeah, well that is how good the game is! FMV of John Cleese is a detail here.
