Wow, that's a name I haven't heard for a while! A.N.N.E had a Kickstarter way back in May of 2013 and it's finally closing in on an Early Access release.
IO Interactive are continuing to improve HITMAN 2 and to let people have a little taste, the first mission is now entirely free. Thanks to Steam Play, it works well on Linux.
Easily one of my top 10 favourite Linux games released last year, Dead Cells, is about to get a huge free update. There's also a sweet mini documentary about the developer.
Heroes Ravage sadly failed the first time around on Kickstarter, it's back and this time they're going the single-player route with their rather unique idea.
BYTEPATH, a retro arcade shooter with a skill-tree inspired by Path of Exile has now been out for a whole year, so the developer has shared some details on how it went.
WarriOrb certainly ticks a number of boxes, this 2.5D action adventure platformer has a gorgeous 3D environment and the developer recently put up a pretty long demo.
