Jupiter Hell from ChaosForge is the successor to DoomRL (Doom the roguelike, now "DRL" after lawyers came knocking), it's a brutal and atmospheric roguelike and you can try it out again.
Just recently, they gave it a pretty big update which comes with Vulkan support by default. However, if that causes you issues you can add "--gl" as a launch option to get it in OpenGL mode.
That's not all! They've also pulled in Mark Meer (Commander Shepard - Mass Effect) to be the voice of "JupiterGuy", with some colourful voice lines which can be tweaked to be less foul if you wish. Additionally, a new and more difficult ULTRAVIOLENCE level is available for those who really like a challenge. There's also SMGs, each class now has a Skilled trait that improves their class active and passive abilities and quite a few other smaller changes.
Free to try across the whole weekend, ahead of the Early Access release on August 1st. Just like the previous times, you do need a special Steam key to access the free demo. You need to hop onto their Discord Channel and message the "CRI Command" bot with the code "!Hell4U". It will then send you a Steam key instantly to access the demo.
It's definitely worth spending a few hours with this weekend, it's quickly becoming my favourite roguelike. Atmospheric, brutal action, it looks damn good and for me the Linux version runs amazingly.

Note: I personally pledged during their Kickstarter, but the developer gave me early access to test it after the campaign was finished.
