In the 22nd century, the Federation of Earth deploys its ultimate weapon: Gunner, a cyborg guinea pig built to repel the Terranublans, a fanatical reptilian race that worships a rogue AI bent on galactic conquest.
Guinea Pig Gunner is an explosive side scrolling action adventure that fuses precision platforming with a massive arsenal of weapons.
This playtest preview build includes two levels: Echo Mountain, where Gunner must scour ancient ruins to activate planetary defense technology from a lost civilization, and St. Athens, a volcano that the Terranublans are trying to weaponize against the inhabitants of Earth.
Key Features
- Move With Style: Run, jump, dash, wall climb, and teleport across 12 sprawling stages, from erupting volcanoes to frozen wastelands and futuristic metropolises.
- Bring the Firepower: Rockets, grenades, flamethrowers, firebombs, and more. Over half a dozen weapons give you plenty of ways to shred enemies.
- Aim Anywhere: Full 360 degree aiming with mouse or controller for precise, responsive combat.
- Teleport to Victory: Blink through walls, telefrag enemies, ambush squads, and solve environmental puzzles with your teleporter.
- Enemies That Hunt You: Terranublan forces chase you down on sight, striking from the air and ground, forcing constant movement and quick reactions.
- Twelve Massive Stages: Battle through handcrafted environments filled with enemies, traps, platforming challenges, and climactic showdowns.
- Replay and Mastery: Hidden secrets, branching paths, and combat variety encourage experimentation, exploration, and speedrunning.
Guinea Pig Gunner is a side scrolling shooter unlike anything you've ever played. Fast movement, a deep arsenal, aggressive enemies, and layers of replayability combine into a fresh, high intensity action experience.
