It couldn’t be any more explicit, but Tammeka is teasing a Radial-G title for Google Daydream over Twitter.
The Radial-G series has been released across a variety of VR headsets, san Playstation VR, Samsung Gear VR and Google Daydream. The UK-based VR company released Radial-G Infinity on Google Cardboard, and Rading-G Racing Revolved on both Steam for (HTC Vive, Oculus Rift and OSVR) and Oculus Store (Oculus Rift).
Playstation VR, Gear VR both has a Radial-G titles in the work though. PSVR will have a port of Radial-G Racing Revolved somewhere this year (It was originally planned for early this year, but it has been quietly delayed), while Gear VR will receives an enhanced port of Radial-G Infinity (titled Radial-G Infinity X). That leaves Gear VR to be the only headset with no Radial-G, but it looks like things are about to change with the tease.
Considering all the titles announced, my guess is that they will be announcing Radial-G Infinity X, the Radial-G title scheduled for Gear VR, will be announced for Google Daydream soon. I’ll report back when they have formally announce something.
