We've always seen Subvert as a project rather than a stand-alone game. The RTS version of Subvert was meant to be a smaller-sized portion of the project (that could stand on its own). However, our heats have always been in the FPS version of the game, which is where we're headed now.
Honestly, at this point, just about everything is subject to change, but we're back on the tactical FPS route. We will incorporate some of the cool mechanics we developed for the RTS, but it will be first and foremost a tactical FPS.
Our #1 priority is to get the smallest possible playable product done and in the hands of our followers for tweaks/feedback/tuning. I think the indie community understands, this is not going to be a mega cinematic experience, so we can release the important parts of the game (THE GAME ITSELF) as early as humanly possible and let everyone in on alpha testing.
That's it for now, we intend to share more info as it becomes available, but I just wanted to clear this up because official update was that we were making an RTS.
