Hell Followed is the second DLC for Doom (2016). It includes three new multiplayer maps called Argent Breach, Molten and Orbital, a playable version of the Cacodemon, a new weapon called the Reaper, and a new equipment item called the Threat Pulse. A 'Cyberdemonic' armor set is also included, as well as additional taunts and hack modules.

You’ve come here for a reason. The Union Aerospace Corporation’s massive research facility on Mars is overwhelmed by fierce and powerful demons, and only one person stands between their world and ours. As the lone DOOM Marine, you’ve been activated to do one thing – kill them all.
