Phobos Down is a top-down arcade shooter on Steam that launched as a paid game but has now switched to a free-to-play model. Solo developer Mikko Rytkönen released the game on Steam in December 2025 and has updated it several times since. In terms of gameplay, Phobos Down takes a slower-paced approach to the shoot ’em up formula, asking players to be more tactical and strategic.
In the developer’s own words, Phobos Down is “more like a classic arcade high-score shooter game with customizable weapons and procedurally generated game runs.” Players must complete missions with the highest score possible without dying. One feature that might set Phobos Down apart from some other top-down shooters is the lack of time limits, allowing players to approach each mission at their own pace and develop a unique play style.

Joining Steam’s roster of free-to-play games on October 1, Phobos Down is now available to all users at no cost. Developer Mikko explained, “The main reason for this change is very low sales.” He noted that while he never expected to make a huge profit from the game, he initially released it as a paid title to learn how Steam’s publishing process works. It is also worth noting that Phobos Down was designed specifically with the Steam Deck in mind, and according to the developer, it runs great on the device.
Phobos Down features procedurally generated maps and missions, helping keep the gameplay loop fresh and varied.
The protagonist of Phobos Down is trapped on an alien planet filled with hostile creatures of various shapes and sizes. Players have three primary weapons: a shotgun, a rifle, and a grenade launcher. And they have plenty of opportunities to upgrade them, adding a roguelike game vibe to the overall experience. More importantly, Phobos Down features procedurally generated maps and missions, helping keep the gameplay loop fresh and varied.

As a small indie game developed by one person, Phobos Down may not have many players at the moment. However, it features weekly challenges that rank players based on their highest scores. Perhaps the switch to a free-to-play model will help the game attract a larger player base and keep its leaderboards more active in the coming days. Phobos Down is available on Android, too, so fans looking for a free game to play on their handheld devices may also benefit from the removal of its price tag.

Valve’s free-to-keep promotions aren’t the only way to claim free PC games on Steam. Players should also keep an eye out for previously paid games that become free to play. Cyberfrags, H-Hour, and Jump Adventures, along with Phobos Down, are all examples of games that once cost a few dollars but are now available to Steam users at the tempting price of $0.00.
