Works great.
The game was locked to the resolution that the Steam-Deck uses. This happens all the time. I belive, that this is a bug in the current version of Steam, not the game.

In-game 40 FPS cap
I had to swith to GE-Proton to get the prerequisites to install without crashing. Ran fine with vanilla Proton afterwards.
Notes/Journal entries
As with most UE4 games on Deck, performance is pretty terrible. 60 FPS at Medium graphics is barely doable and will drain the battery in 90 minutes flat.
Very long delay when the game is first launched, sitting at a black screen (~30 seconds). On subsequent launches, the delay is maybe half as long.
Only after New Game+ 3 (~50 hours gameplay), game would crash during levels and arenas
With Proton 7.0-6 and Experimental, there was noticeable input lag and slight stuttering, both completely fixed with GE
Didn't launch with a regular proton.
New version comes with an engine update which fixes most issues.
The mouse cursor in the menu now moves correctly and the notable performance drops in bigger levels seem to be far less common.
On a decent desktop things are mostly okay, but on steam deck the performance isn't where it should be.
Mouse is usually extremely stuttery and unresponsive in menus
A decent framrate will hold if I don't look around. The faster I look the further performance tanks. Issue is persistent on three different nvme ssds AND on steam deck. I believe this is a proton or game optimization issue. I don't believe performance is stable enough for deck verification.
On desktop I tried wayland, x11, and using gamescope under both. All issues persisted.
Black screen for a second and then crash. Older versions such as 6.3 and 5.13 didn't worked out for me
Shows banner on startup and that's it.
Still like-native, however one weapon may make game prone to crashing.
Only times I've had crashes were from the gravity staff. Otherwise no issues.
Like-native experience.
Switching workspaces in KDE Plasma would ocassionally cause head position to stay, leaving the mouse to act as a cursor in-game. Fixed by swapping back and forth again.
Decent performance drop on trying to stream the game through Discord.
Overall runs very well without any tweaks.
Mouse was strangely laggy in the menus.
Game slows down significantly during later levels with lots of particle effects/enemies on screen, but other than that it runs alright with dynamic shadows turned off.

Put in a solid 40 hours with no issues.

XBox controller works fine and smooth, I had issues with my mouse feeling laggy.
XBox controller works smooth out-of-the-box, mouse control is laggy.
After certain patches, the game runs smooth.

Slowdowns on a couple of maps, likely due to particle amount and random map generation
Three crashes over 40 hours of playing
Nightmare Reaper has gamepad support out of the box, but it also supports hybrid input. Flick stick + gyro works nicely.
Good gamepad support and no noticeable issues, great experience on the Steam Deck.

Despite being out of early access, still lags and crashes as much as ever
Mouse is jittery to the point of being borderline unusable in menus
Some levels run alright, some stutter like nobody's business
Game crashes randomly at the drop of a hat, in levels, in menus, in minigames
Game also takes ~3 minutes to load to an unresponsive black screen, then another 2 minutes to actually start running. When it crashes, it can't be relaunched for ~10 minutes for some reason. With its level of instability, it's almost impossible to play for any prolonged length of time.
Did a complete replay on Linux, works great!
Ran perfectly out of the box, no issues in over 2 straight hours of playing
Runs flawlessly
I did experience minor Framerate-drops, but I highly assume that these are either connected to the game itself or my hardware, since I experienced these also on Windows 10.

Seamless, like-native experience
I'm confident that the issues I've encountered were the result of bugs, not Steam Play. Those issues were sound cutting out when too many sounds were playing at once (for example, using miniguns with the Reflection powerup, or 20+ explosions at once) and poor framerates in some areas and situations. Regardless, these were rare issues that did not impede play.
Runs smooth, loading times sometimes increase as you play longer.
The load times of the game take a very long time after an extended session, also while trying to stream this on Discord I couldn't start the stream, it would freeze Steam and Discord, when trying to stream through OBS the same thing would happen. To resolve that, start the game first, open OBS, select the game, then stream.

runs perfectly

Via Steam, takes an inordinately long time to launch and runs at an utterly unplayable framerate. Via Lutris, requires DXVK enabled to fix lighting and rendering glitches, and runs at a not great but perfectly playable framerate. Still nowhere near native performance. Crashes or hangs now and then, which may be due to Early Access rather than Proton.


The game hard freezes my computer upon start. Actually I have the same problem with "Amid Evil", so I don't know if the problem comes from using and Intel GPU, the Engine, or a combination of those two.


Run perfectly fine out of the box. Had a few crashes that, according to the patch notes, have been dealt with by now. A few drops below 60fps here and there, but windows-folk are reporting slowdowns/performance issues too. Probably due it being still a WIP. Didn't try any tweaking as it ran fine on my PC.


The game works fine except for the occasional crashes. The steam forms seem to show the instability is also present in windows.
