N-iX performed a number of R&D activities when working on this game. First, we gathered a group of experienced game developers and 3D artists, brainstormed ideas for a multiplayer VR game, and selected top 5 game concepts. Then we created basic prototypes, conducted a playtest and, finally, chose the VR shooter as the best idea.
The team used Unity as the main game engine along with Photon Engine framework for multiplayer functionality. At first, the game supported HTC Vive and Oculus, and later we added PS VR and Gear VR headsets.
