AIMHEAD
INVADE THE NULL//SYSTEM. Every vulnerability makes you stronger — and brings the system closer to collapse.
Free, browser-playable PSX-style FPS roguelike. Fight through a nighttime container yard, break the rules, and survive one more wave.
HACK//BREAK
Choose from 57 exploit cards across vision, aim, weapons, body upgrades, abilities, and system effects. Every card grants power, adds a SYSTEM COST such as more or faster enemies, and raises INSTABILITY. Above 100%, the system breaks into chaos events.
From wave 2 onward, an extra LEVEL UP card appears halfway through each wave. Cards reveal one by one.
SURVIVE THE WAVES
- Build your loadout: Start with an AK-47, then collect an SMG, shotgun, pistol, grenades, health, speed boosts, shields, and exploit chests.
- Fight the whole system: Face grunts, rushers, bombers, shield enemies, snipers, heavies, and drones. Use explosive barrels and enemy blasts to turn the arena against them.
- Beat the bosses: Every three waves, take on ROOTKIT, KERNEL_PANIC, DAEMON.EXE, ZERO_DAY, or BLACK_ICE.
- Keep the streak alive: Chain kills to charge OVERCLOCK, four seconds of slow motion. React to double drops, falling barrels, and marked targets.
- Never stop moving: Sprint, slide, bunny hop, and air strafe through the container yard.
The ECG HUD turns your health into heartbeats per minute. An online leaderboard tracks wave, kills, headshot percentage, bosses, and kills by weapon. The synthwave soundtrack is generated live by the game.

I feel like the text on the cards is harder to read because of the lines that go across the screen, maybe keep the lines but lower there opacity or make them smaller
Yeah, I’ll lower the opacity and make them thinner. Thanks!
Fun but I feel like as soon as I grab the shotgun the run is cooked...
Thanks for the feedback! I’ll take a look at the shotgun balance.
