Doom Eternal's gameplay debut at QuakeCon 2018 managed to hit all the right notes while highlighting the carnage of a one-man war against the forces of Hell. The follow-up to Doom (2016) manages to make its predecessor look tame by comparison, with a set of new abilities and weapons, along with an expanded traversal system through a grappling hook attached to a shotgun. With the return of the Doom Slayer--a reimagined take on the enigmatic yet equally dull DoomGuy of the original games--the developers want players to feel even more immersed in the role of the silent and imposing protagonist.

One of the biggest surprises is the new Invasion mode to complement another robust campaign, bringing enemy players into a traditional single-player experience. To go with greater focus on unique content, Doom Eternal will drop its predecessor's SnapMap mode, in favor of new DLC focusing on the exploits of the Doom Slayer. In our talk with creative director Hugo Martin and executive producer Marty Stratton, they spoke about how much the game has changed since its 2016 predecessor, and why its new features will make it more exciting than ever.
