There's always going to be problems when developers are able to set anything they like on Steam with no proper checks from Valve. Despite listing SteamOS/Linux system requirements and showing a SteamOS icon, BATTALION 1944 [Steam] is not coming to Linux.
For the record, I value what Valve has done for Linux gaming. Their continued effort behind the scenes with VR work, Mesa and so on is awesome. However, that doesn't give them a free pass from criticism when I think they need to step up a bit.
Here's the problem in two pictures:
The game has been showing up like that for quite a long time now. As it turns out, it's not actually coming to Linux with the Early Access release today (or at all).
I posted on their Steam forum to ask them about it back on October 9th, 2017 which never got an answer from the developer. Since then, I've made a reddit post, a post on their official forum, emailed them twice and sent probably 10+ tweets to ask them about it. I also tried their Discord, they didn't reply to a PM there and their actual normal chat was just—terrible, no chance of an answer there due to the types of people that inhabited it.
It was only yesterday (the day before release) in their announcement that they said this:
Good news Linux fans!
Linux distributed server files will be available February 1st for all your dedicated server hosting needs.
After the above, I wasn't too amused to see only server files being mentioned and no client. Today, we finally have a real answer. I managed to get their Lead Programmer to answer on Twitter, to confirm it is not coming to Linux.
I'll be honest, I'm quite sad and annoyed about this. I was very excited by the game myself, but it goes to show that you should never just trust what the Steam store shows.
What I will say, is do not give the BATTALION developers a hard time over this (especially since they didn't take pre-orders, so no one has lost money through Steam in this case). They still should have noticed what they had done, but ultimately it's not their store. Their communication was still poor though, they should have done better. I'm using them as an example to highlight the issue, but they're certainly not alone in this. This is not the first time it's happened and I've no doubt it will happen again, until Valve has some better verification in place to make sure games on Steam are actually coming to the advertised platforms.
This is where GOG does better. Even though they end up with less games, their attention to their store is a lot better. Valve, if you're reading, this sort of thing shouldn't happen. Please do better.
Ps. Day of Infamy is a good WWII shooter and supports Linux.
