CliffyB and his team at Boss Key Productions are still tap, tap, tapping away with "Project Bluestreak", but the team showed it off during PAX East, releasing a proper teaser of it on YouTube.
As you can see, Unreal Engine 4 is powering Project Bluestreak, a new first-person arena shooter. It looks pretty incredible, but I'm hoping it's more than just pretty graphics. I'd love to see some destructible environments, and more. But, for just the graphics alone, Project Bluestreak is shaping up beautifully for its pre-alpha state.
