EVECTOR, Acid Thirst (v0.9.7)

A hostile alien planet turns survival into a grimy, fast-moving firefight, with corrosive landscapes and hostile lifeforms standing between you and escape. EVECTOR, Acid Thirst is a modern-classic first-person shooter built around the feel of late-1990s and early-2000s PC action games: direct, arcade-minded, and unconcerned with cinematic hand-holding. Its world is harsh rather than pretty, leaning into a deliberately brown, industrial retro look that gives the acid-soaked wilderness an appropriately desolate mood.

The objective is simple: push through dangerous regions, kill whatever blocks the route, and find a way off the planet alive. Combat centers on dealing with Aciders and vicious native fauna across a sizeable nine-square-kilometer open map, so encounters are not restricted to a linear corridor of arenas. Fifteen enemy types provide variety in the threats you face, while two controllable vehicles—a boat and a sliding transport—make traversal across the hostile terrain more than a matter of running from one fight to the next. The design favors immediate shooting, movement, and environmental navigation over complicated systems, making it easy to understand while still asking players to stay alert in unfamiliar territory.

What separates EVECTOR, Acid Thirst from a purely retro shooter is its combination of old-school presentation and a genuinely broad playable space. Rather than imitating the cramped level design of its inspirations, it uses modern engine technology to let players roam a larger, more open alien landscape between firefights. The rough-edged visual style and straightforward premise will appeal most to players who miss the blunt momentum of older FPS games and want a lesser-known alternative after exhausting the usual classics. Fans of no-nonsense arcade shooters, strange sci-fi settings, and retro PC aesthetics are the natural audience, while players expecting polished storytelling or deep RPG-style progression may find its appeal more limited.
