I actually had never heard of The Colony. Checked it out and it's awesome!
That cannot be an accident! Sirenum is identical to Colony, those lines, starship design.
Anyway SIrenum works great on linux through wine. I had nasty framedrops on few angles with shadows(maybe they are blurred little too much? but I use intel hd5500 so it is understandable) it would be cool to have option to lower the shadows quality and video resolution.
Game is amazing, Great voice acting, sound design and music. Spot on. This could be big. You pulled me in.. You have green light from me.
