Sony has shown off what appears to be the first gameplay footage from its new PlayStation 4 console with a demo of the upcoming Killzone: Shadow Fall game. Killzone is developed by Guerrilla Games and is a first-person shooter set in a futuristic environment. Sony spoke to great length about the PlayStation 4's hardware capabilities, and Killzone takes advantage of them with very detailed environments, loads of lens flare, depth of field effects, and realistically modeled water effects. It's hard to say exactly how it compares to the current generation of consoles until we see it close up in person, but you can get an idea of what gaming on the PS4 is like in the demo video below.
