Echo just received its very first gameplay trailer, giving players the first look at the Unreal Engine 4 stealth game from developer Ultra Ultra. The game tasks you with exploring a strange palace floating through space, but with one major catch. The palace seeks to destroy you, and uses so-called echoes of your character to do so.
That means that every time you vault a ledge, hide behind something or use your weapon, the echoes will learn and alter their behaviour accordingly.
Echo is coming to PC next year, as well as "unannounced consoles", possibly referring NX or maybe it just means consoles to be announced.
