Universe Sandbox 2 is a physics based space simulator. We never got the original on Linux, but as teased the developers are delivering with Universe Sandbox 2.
Steam's Early Access is filled with games these days that are annoying to cover due to missing assets, bugs, bad performance and unfinished gameplay mechanics. In my opinion only few games out there are worth picking up. And I believe Ziggurat is one of them.
In Mini Metro you are tasked with designing your own subway system for a growing city. It looks simple, but once you get into it not only is it addictive, but it's generally awesome too.
Crawl is the local multiplayer dungeon crawler where your friends control the monsters! It's a really interesting looking game, but considering it requires local multiplayer we are a little skeptical here.
We mentioned before that Knight Squad was coming to Linux, and here it is with the latest update! Knight Squad is a 1 to 8 players game that can be described as SNES era Bomberman meets Gauntlet. Play as a Knight in the arena and defeat your opponents using epic weapons and power ups.
Black The Fall seems to have suffered the same problem a few games do when they add a Linux version to an existing game on Steam, and that's zero exposure. So, it was one even we managed to miss.
NeonXSZ is quite a unique FPS set in cyberspace that we have covered before, but it's come a long way development wise and will be heading to Steam in August.
Frozen Cortex is the brand new game from Mode 7 who you will remember created Frozen Synapse. Two days ago they added the Linux builds to their new game!
Darkwood is a dark survival game that blends a few different types of games together, and originally Linux was a delayed release, but they actually delayed their own release so that Linux is now a day 1 release. They have now finally given an Early Access release date with a fancy interactive trailer.
The developers of DubWars noted last month that in the next update a Linux version is on the table. We love games that mix music into the gameplay and DubWars could be a winner.
