CivCity: Rome

Halo: Doom Evolved is a large-scale mod for GZDoom that brings the Halo universe into Doom. Expect over 54 weapon types with realistic animations and alternate fire modes, 3 unique Spartan classes each with their own movement mechanics (from bunny hopping to grappling hooks), and 8 flexible arsenal customization modes.

Epochs of Enmity — an unofficial "6th episode" for Quake, featuring 10 atmospheric maps in the spirit of the original. The player travels through time across varied locations — from ruins to castles. Classic gameplay blends with modern ideas, improvements, and thoughtfully designed combat.

DOOB is a deliberately "terrible" mod for DOOM — and that's exactly what makes it wonderful. The game's graphics use intentional primitivism that transforms the gritty shooter into an absurd comedy.

Azure Sheep: Enlightened - a remaster of the original Azure Sheep mod with numerous changes affecting textures, HUD, weapon mechanics, levels, NPCs and much more.

Half-Life: Walter is a story-driven mod in which the player takes on the role of a scientist caught in the middle of the Black Mesa incident during the resonance cascade. Following the disaster, the protagonist becomes one of the survivors and is forced to find a way to escape through the destroyed and dangerous sectors of the complex.
