While we are waiting for Doom Eternal's release on March 20, 2020, the modder Officer D is developing Doom Exp, a mod that aims to replicate gameplay elements from the still unreleased game. The mod comes packed with a xp/rank/reward/mobility modification with visual/sound/text notifications, a custom "Doom Exp Settings" menu with many adjustable settings and keybindings, edited sounds & effects, improved mobility (sliding, dashing, wall latching), more gore - etc. Not to mention Doom Slayer's new additions to his arsenal: from the shoulder cannon and wristblade, to even the Crucible Sword itself, all that paired with new power ups to make the gameplay even more enjoyable. Doom Exp is available both on Modb and ZDoom Forums.
