Steam is running a limited-time giveaway for One Gun Guy, a fast-paced action platformer from publisher Grab The Games. Originally released in 2022 and typically priced around $5 when not discounted, the game can be claimed for free until December 18, 2025. If you enjoy quick movement, tight platforming, and arcade-style combat, this is one free Steam game worth grabbing before the offer ends.
One Gun Guy is built around a simple but fun hook: you play as a lone, armed character who has exactly one gun. From there, the game leans into nonstop momentum as you jump through platforming challenges, take down waves of enemies, and face off against bosses. Rather than splitting the adventure across many small stages, the core experience takes place in one large, expansive level filled with obstacles, checkpoints for respawning, and optional secrets to uncover.
Progression comes through upgrades that change how you move and fight. As you collect coins while advancing through the level, you can spend them on perks that noticeably improve mobility and combat. Upgrades include abilities such as double jump, gliding, and magnetism, helping you reach tricky areas, chain movements more smoothly, and handle encounters more efficiently. The level also hides optional areas, and some of those discoveries can even lead to additional boss fights—rewarding players who like exploring off the main path.
The gameplay places a heavy emphasis on controls and speed, and it’s designed to feel snappy once you get into a rhythm. While the standard difficulty may feel easy to some players, beating the game unlocks a hard mode that turns the challenge up significantly and is known for being far more demanding.
Controller players also have a reason to take note: One Gun Guy includes full controller support, which can make the fast movement and platforming feel even more natural depending on your play style.
Since launching on Steam, the game has collected roughly 40 user reviews, with about 65% rating it positively. The most common criticism is that it’s short and can be completed fairly easily on the regular difficulty, while positive feedback tends to center on the game’s controls, movement, and action-platforming loop.
If you like short, skill-focused platformers with upgrades, secrets, and a tougher mode waiting after the first clear, One Gun Guy being free on Steam until December 18, 2025 makes it an easy title to add to your library.
