Evaluation

Project Tachyon launched on February 13, 2025 and received a steady stream of updates in the months that followed. The developer shipped balance patches and bug fixes shortly after launch, then added a twin-stick shooter control scheme and codex illustrations in Version 1.1.0b (March 7, 2025). A content update in Version 1.2.0 (May 23, 2025) added two new weapons (Riff Breaker and Bluewing Hatcher), a new skill, five new items, and a new combat zone. Version 1.3.0 (August 12, 2025) then added upgrade options for all weapons and skills — a substantial expansion of the game's build depth. That August 12, 2025 update is the last developer communication on record. As of September 24, 2026, over 13 months have passed with no further posts, patches, announcements, or developer statements. The earlier update pattern saw major content arriving roughly every 2–3 months (Version 1.2.0 in May 2025, Version 1.3.0 in August 2025), meaning the current silence extends well beyond three times that interval. No roadmap, unreleased DLC, or outstanding commitment is visible in the store listing. The developer also made no announcement of future content after Version 1.3.0. The developer stated in March 2025 that they were "dedicated to continuously improving and developing PROJECT TACHYON," but that statement predates the last update by several months and has not been reinforced by any subsequent communication. With silence now far exceeding the historical update cadence and no announced content remaining, the evidence points to the game having reached its completed state with the August 12, 2025 update.

About this game

When the Tamageria Republic faces a crisis with the rebellion of Mainframe OMEGA, an artificial intelligence, they turn to their last resort: a nuclear attack to stop Mainframe OMEGA.

Countless casualties occur in the aftermath, and Commander Elina secretly activates "Project Tachyon" to avoid the danger of a nuclear winter.

Sigma, an agent of Project Tachyon, studies the future and travels back in time to solve problems based on their observations. However, they discover a shocking truth during their mission...

Dynamic combat action using melee and ranged weapons

Engage in combat filled with extravagant action scenes as you wield an array of weapons in diverse situations.

Use melee weapons to block the enemy's barrage and use ranged weapons to subdue them from a distance.

Roguelite gameplay system

Choose from over 200 powerful genes in 10 different categories and upgrade according to your preferences.

Unlock powerful synergistic effects by gathering various types of enhancement genes.

Watch out for malicious genes, a key element in this Roguelite that thrives on the blend of luck and skill.

As you equip more enhancement genes, your chances of manifesting a malicious gene will increase.

Be wary as you'll sustain harsh penalties if you fail to meet the requirements.

Switch up your combat style with an array of weapons that can be randomly obtained at certain stages.

Deal with your enemies strategically by adapting to each situation–use an electric saw that slices incoming bullets or an acid sprayer to weaken the enemy’s defense.

Find an efficient route to navigate the map that varies every time you play.

You can save your stamina to challenge the boss, or take on more risks for a greater payout. It is your choice.

Experience unique battles by upgrading weapons

Unlock and upgrade various weapons through quests.

More weapons will appear by unlocking them before each stage begins.

Modify your weapons and enhance by battle experience.

Giant boss raid

Giant mutants, the followers of the artificial intelligence Mainframe OMEGA, lie in wait to interrupt Sigma's advance.

Unlike normal enemies, the Giant Boss uses a variety of gimmick patterns to threaten you.

Upgrade your enhancement genes and collect various weapons to effectively combat the boss in any situation!

Engaging narration through Roguelite

Every character, including the protagonist, has a hidden past, trauma, and unique personality traits.

Only Sigma, who has the ability to retain memories, can continuously travel through time to understand and forge deeper relationships with these characters and successfully complete the project.

An intriguing story through time-traveling

Travel through time and gather clues from the future, then return to the past to unravel the truth.

Seemingly insignificant details overlooked in the past will deeply impact the future.

Collect the clues amidst an ever-changing landscape to successfully complete your mission!
