Overview
AI.VI is an action-shooter with tower defense mechanics developed by Out of Time and published by indie.io, released on March 18, 2026, for Windows, macOS, and Steam. The setup is simple and immediately compelling: a mercenary robot named AI.VI has been quietly mining in the desert, keeping his head down, when the P.A.S.C.A.L. Gigacorporation rolls in to strip the planet bare. Retirement ends. Violence begins.
What makes AI.VI stand out from the crowded indie shooter field is how it forces players to split their attention. This is not a game where you can sprint through corridors and solve every problem with accurate aim. The tower defense layer means positioning, resource management, and defensive planning matter as much as reflexes. That combination is harder to pull off than it sounds, and the fact that Out of Time built it around a robot uprising against corporate overlords gives the whole thing a personality that most genre hybrids lack.
Gameplay and mechanics: how does the FPS tower defense mix actually work?
The core loop in AI.VI sits at the intersection of two genres that rarely share space. In FPS mode, players control AI.VI directly, moving through environments, engaging corporate enemies up close, and handling threats that require a more personal touch. The tower defense layer runs alongside that, asking players to place and manage defensive structures to hold positions while waves of P.A.S.C.A.L. forces push back.
Key mechanics include:
- Direct FPS combat against corporate enemy units
- Tower placement and defensive structure management
- Resource control tied to the planet's production systems
- Wave-based enemy encounters requiring both offense and defense
- Strategic positioning across the game's environments
The balance between these two systems is where the game earns or loses players. Leaning too hard on either side means the other falls apart, which is exactly the kind of design tension that makes strategy-shooter hybrids interesting when they work.
World and setting: a planet worth fighting for
The fiction underneath AI.VI is doing real work. P.A.S.C.A.L. is framed as an intergalactic megacorporation that moves from planet to planet, converting everything into profit and leaving nothing behind. AI.VI's home world is next on that list. The protagonist was never supposed to be a problem; a mining robot running out the clock in the desert is not exactly a threat assessment priority for a gigacorp.
That miscalculation drives the entire game. The world feels lived-in precisely because AI.VI was living in it before the shooting started, and the corporate invasion gives the environments a before-and-after quality that grounds the action in something with actual stakes.
Innovation and unique features
The genre combination in AI.VI is not just a marketing hook. Blending FPS action with tower defense strategy creates genuine mechanical friction that neither genre produces alone. Players have to make decisions under pressure that are simultaneously tactical and immediate, a rhythm that rewards players who can context-switch quickly.
The class framing of the story, a worker bot seizing the means of production from a corporation that treats planets as assets, adds a layer of thematic coherence that most indie shooters skip entirely. It is not subtle, but it does not need to be.

Conclusion
AI.VI is a focused, genre-blending shooter that pairs FPS combat with tower defense strategy and wraps it in a premise that has more personality than most indie games manage. The P.A.S.C.A.L. corporation makes for a satisfying antagonist, AI.VI himself is a genuinely interesting protagonist, and the mechanical combination of direct combat and defensive planning gives the game a distinct identity in the action-strategy space. Players who enjoy games that demand both aim and forethought have a clear reason to check this one out.
