Games have explored the idea of combat in outer space pretty thoroughly over the years, so one could be forgiven for thinking that the setting is pretty much tapped out at this point. However, this actually isn’t the case, and Studio Surgical Scalpels’ Boundary is proof of that. Check it out in the new Fire Fall trailer.
Zero-G combat with a Mouse and Keyboard is not as easy as one would think but the game is a nice variation on FPS gameplay.

In space, no one can hear you 360 no-scope.

Miles @ FG: Fast-paced and gravity defying, first-person-shooter Boundary will test and your skills, and maybe your patience. The Finger Guns review.
Looks great, sadly they switched their main platform from PlayStation to PC and their support staff dodge questions related to the PS release now.
PC has had several betas to date, so I wouldn’t be surprised if this ends up not making it to PlayStation in the end or is, at the very least, released way down the line following the PC release.
This game is incredible. I’ve been addicted since it came out. It scratches an itch that I haven’t felt in a long time. For early access, it and looks runs great. It does need some polishing around the user experience but I’m impressed. Can’t wait to see where it goes.
