Doom Eternal

Doom Eternal is an upcoming reboot sequel to the 2016 Doom reboot. The game will launch on March 20, 2020 for PlayStation 4, Xbox One, Nintendo Switch, PC, and Google Stadia.

Singleplayer
A new feature added is the ability to invade another player's game, in a system called "Invasion." Invading players can team up and spawn in a player's single-player playthrough as enemies.

The Doom Slayer moves faster than in the previous game, and is now equipped with a shoulder cannon on his left, which can be used to fire grenades or a burst of flame. It operates on a cooldown.

There is an increased focus on mobility in the game. The Doom Slayer gains a grappling hook (via the Super Shotgun), the ability to perform short boosts along the ground, and swing from poles. Two boosts can be used at a time before having to recharge.

Gun modifications return from the previous game.

A new feature is an extra life system. This has been designed as an augment to the checkpoint system, where players can get a respawn without having to go back to the last checkpoint.

Multiplayer
Doom Eternal will have a multiplayer system. Unlike its predecessor, it will be developed in-house by Id.

Plot
Set 8 months after Doom 2016, It takes place on Earth, with the forces of Hell having overrun it. Other locations have been revealed, such as a human base on Phobos, new regions of Hell, and previously unseen locations within the franchise. The developers tease that the game will feature a more in-depth lore of the Doom universe. Similar to the previous game, Doom Eternal features a codex system. This is part of what Id is calling the "Doom Universe." It is confirmed that the Doom Slayer will fight both the force of hell and heaven.

Additional story content will be released post-launch.
