The idea of an indoor FPS system is something that has been around for a while.
Valve has been experimenting with it for years, but this is the first time that we’ve seen an indoor system in action.
While the demo was impressive, it’s not quite ready to release for public consumption just yet.
That’s not to say it’s a bad thing.
In fact, the company has been working on a game engine specifically for indoor gameplay that will allow players to control their own spaces in an enclosed environment.
The company has already been working with the Valve team to help them figure out how to make that work, so we can expect to see the first real indoor FPS in the near future.
