Alkaline

The mod includes 13 sci-fi levels, each offering unique architectural solutions, atmosphere, and secrets. Among the standout maps: Dancing in the Golden Sun — for its non-linearity and thoughtful progression, Tellus Terminus — for its scale and gravity shifts, Derelict Freighter — for its atmosphere and balance, Foundation for Corruption — for its complex combat situations, and Geothermal Outpost — for its vertical design and exploration. Some levels feature double and triple jumps, variable gravity, and elements of realism — such as ladders, railings, control panels, and scientists in lab coats, reminiscent of Half-Life and SiN.

The enemy roster features reworked and original monsters: Drone, Lieutenant, Prowler, Enforcer, Shambler, Tormentor, and others. Each enemy has unique attacks and behavior — from fast kamikaze drones to heavy mechs with powerful ranged strikes. Many enemies employ special mechanics such as shields, dashes, or homing attacks, and are complemented by new visual effects, animations, and updated sounds.

Alkaline introduces new weaponry, including experimental and energy-based arms, as well as unique pieces like the Cluster Mine Launcher, effective against groups of enemies and reinforcing the mod's sci-fi style.

This is one of the best sci-fi base-themed mods for Quake, combining meticulously crafted architecture, intense combat, diverse secrets, and expanded modding capabilities — including new AI mechanics, tools for controlling enemy behavior, and building complex scenarios. The mod is a must for all Quake fans seeking the highest level of creativity and map design.
