About this game

The year is 2025 in the United States. You're a hacker and answer to no one. Use your skills to rig elections, expose corruption, steal money to upgrade your tools, and much more in this immersive simulation. SIGKILL gives you choices and control. What you do with it is up to you. Strap in because you're in for a wild ride. 

HACK ANYTHING

SIGKILL drops you into the modern-day simulated United States that lives and breathes on its own, and you have control over what happens...but don't get caught. Hack corporations, banks, drones, and nuclear reactors, all to achieve your goals.

FUN FOR EVERYONE
SIGKILL offers multiple ways to hack the same networks. In Operator mode, find clues and solve puzzles to affect the world around you.

A LIVING WORLD
The simulation underneath SIGKILL is powered by neural networks trained on historical events. Politics shift. Markets react. Tensions between factions rise and fall on their own. You can affect all of these, and if you're really good, you will be the one pulling the strings.

AGENT OF CHAOS OR VIGILANTE
SIGKILL is politically and morally neutral. Go whatever direction you desire. The choice is yours.

REAL HACKING
SIGKILL's hacking is built on real methodology and tools. Scan targets to discover services. Enumerate to find weaknesses. Research CVEs in the in-game ExploitDB. Deploy your exploit. The tools and workflow mirror actual offensive security, simplified enough to be fun but deep enough that OffSec professionals will feel right at home.

EMERGENT GAMEPLAY
What you do is your choice. The game will feed you missions based on your actions. Want to be a double agent and pit two factions against each other? You can do that. Want to rig an election or expose corruption? You can do that too.
