Protocol: Kill Switch is a fast paced action roguelite. As a sentient virus, you must tear through a collapsing mainframe, outrun a relentless digital swarm, and trigger the Kill Switch before the system deletes you forever.
The rules of the mainframe are simple. Just pure action:
Fight the Swarm: Blast through waves of security programs in high contrast digital arenas.
Level Up Mid Run: Collect shards to level up and choose randomized perks on the fly. Will you take extra damage, faster movement, or chain lightning bullets?
Power Up Shrines: Find high risk stations to overclock your code. Get massive buffs but be prepared for "glitch" penalties that mess with your movement.
Permanent Progression: Use your hard earned Data Shards between runs to permanently boost your stats and unlock a devastating armory of new weapons and permanent upgrades.
The DAEMON Companion: You don’t breach alone. Deploy a loyal digital companion that provides autonomous cover fire. Upgrade its sub routines to match your playstyle.
Digital Noir Aesthetic: Experience a striking world of Cyan and Magenta. Watch as enemies shatter into ASCII fragments and weapons tear holes in the floor grid.
Evolving Arsenal: Discover weapons that feel like hardware failure. From the Data Breaker shotgun to recursive Logic Bombs, your weapons are the exploit.
Steam Deck Optimized: Built for portable breaches with full controller support, dynamic glyphs, and high legibility UI.
In this mainframe, death is just a Hard Reset. Get stronger. Go deeper. Break the system.
