About PROJECT TACHYON

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!

[h1][b]PROJECT TACHYON? Neon Time-Loops & Gene-Powered Gun-Fu![/b][/h1] "A roguelite rush where katana parries meet bullet-hell barrages—and every timeline begs for one more run." [h1][b][1] Intro : [/b][/h1] Sigma’s mission is simple: jump back, stop rogue AI Mainframe OMEGA, and prevent nuclear winter. Simple—except the future rewrites itself every time you die. PROJECT TACHYON fuses Metal-Slug-style run-and-gun with Hades-like loop design and a heavy splash of cyberpunk flair. [h1][b][2] Game Experience : [/b][/h1] Combat is gloriously kinetic. Melee weapons can slash bullets out of the air while ranged guns melt crowds from afar. Switch on the fly to match each encounter. Over 200 enhancement genes in ten categories push you toward wild synergies—chain-lightning blades, ricochet rail guns, vampiric shields. But stack genes carelessly and malicious variants appear, saddling you with painful debuffs that demand skillful play. Every procedurally shuffled map hides weapon chests, lore nodes, and risk-reward paths—burn stamina for a boss shortcut or clear extra rooms for loot? Your call.

Project Tachyon is a really fun side-scrolling rouge-lite shooter that reminds me of an old flash game I used to play on Armor Games called Raze. I really recommend playing Project Tachyon with a Keyboard+Mouse for all the extra buttons, but I'd experiment with the two controller set-ups to find what works if that's not an option for you (and the developers included an auto-aim option for additional help). The guns, abilities, and perks are all really enjoyable to wield in-between each of Project Tachyon's runs. Each of these can be upgraded using the currency you acquire across different runs that isn't impacted by Tachyon (time) travel when you perish. All of these can feel a bit lackluster at first, but once you start upgrading each gun/ability/perk a bit more, you'll quickly find your favorites and enter into power fantasy mode. I found use for even a gun that deals no damage through the primary fire, which really surprised me. Every run has multiple routes per zone alongside randomized events with a set boss at the end of each zone, making each route plan a strategic risk-reward. Do you go for the extra battle to get a new gene/currency or would a shop be more beneficia…

the way this game incorporate a story into a rogue like genre is really smart, using time travel! I am hooked to the story, which is a strange way to say about a roguelike game. it is also fun and challenging, I only wish that there was a wider selection of weapons to choose from and a way to test each weapon projectiles before unlocking them. but overall definitely recommend this awesome game.

time traveling as a last resort in a war might be interesting but fatal if rigged yet another rogueLITE with meta progression but has a solid melee/gunplay and a interesting way of risk and reward on building during a run sadly a very predectible story but had a good time here (dunno if i wanna do all the difficulties, stages are a bit repetitive and needs more varitiy/ways to get stuff easier) its nice

Very good roguelite action platformer overall. Controls could do with some streamlining though, there's barely enough buttons on modern controllers to cover all the functions.
