A compact twin-stick shooter that quietly earns your respect: tight controls, a surprisingly story-driven campaign, and a time-as-health system that makes every wave feel genuinely urgent.

I have a soft spot for the twin-stick shooters that nobody argues about at the table, the ones that don't make best-of lists but sit in your library and pull you back in for one more wave at midnight. Tachyon Project is exactly that kind of game. It puts you in control of Ada, a self-aware hacking program who wakes up locked out of her home server and starts tearing through corporate firewalls to find the two programmers she calls her parents. It is a small, strange premise for an arcade shooter, told through moody comic-book cutscenes, and it works better than it has any right to. The mechanical hook that separates this from a Geometry Wars reskin is the time-as-health system. Destroying enemies adds seconds to your countdown timer, while taking hits shaves them away. Secondary weapons like freeze bombs and turrets also cost time, which means even your safety net has a cost. It creates a loop where aggression is survival and caution slowly kills you, which I find genuinely satisfying in a way that traditional health bars rarely manage. The weapon loadout system deepens this further: primary weapons unlock across the campaign's ten stages and include machine guns, lasers, shotguns, and missile launchers, while perks let you tune movement speed, damage output, or defensive shields. The customization is real, even if some weapons quickly outclass the others in practice. Enemy variety is one of the game's cleaner achievements. Vortex enemies that pull Ada into their gravity field, stealth drones that only charge you while you're firing, shielded orbs that only take damage when bounced into arena walls, slow serpentine units built to absorb punishment while faster threats swarm around them. The game keeps introducing new types throughout its campaign, and learning each one's rhythm is where the pleasure lives. There are also four bosses, each with a distinct gimmick, and a stealth mode in certain levels where firing your weapon betrays your position, which is a genuinely original idea for the genre even if its execution gets messy in practice. Where Tachyon Project gets more honest criticism is around longevity and polish. The campaign is fairly short, the single rectangular arena never changes shape, and some enemy spawns that appear directly underneath you feel like design oversights rather than challenge. The challenge modes, including endless survival and a one-hit variant, support up to four-player local co-op, which is a genuinely appealing couch option even if those modes don't have deep staying power on their own. The electronic soundtrack is atmospheric and fits the hacking-program aesthetic well, though the sound effects are more forgettable. Steam user sentiment sits at 83% positive, modest but honest for a game this genre-adjacent. If you already own Geometry Wars 3 and Nex Machina, Tachyon Project sits a tier below those. If you don't, or if you want a story-threaded campaign in your arcade shooter rather than pure score chasing, this unpretentious little release from Eclipse Games genuinely delivers on its core promise. It knows what it is, finishes in a reasonable sitting, and the time mechanic alone makes it worth the curiosity. Kai, Scout Team

Solid arcade pick for twin-stick fans who want a campaign hook and loadout depth, not a genre-defining masterpiece.
