About this game
What this game is, in the developer's words
An exhilarating run-and-gun action shooting game based on a Roguelite! Travel through time with Sigma to thwart the uprising of artificial intelligence and fight for the future!
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

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

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.
