About 6K

Step into the heart-pounding world of 6K, the explosive indie shooter forged for Ludum Dare 42’s "Running out of space" theme! This isn’t your typical shooter – in 6K, the very ground beneath you collapses with every step, turning every second into a nail-biting race for survival. You’re armed with guts, a trusty gun, and the quick reflexes only true action fans possess. But here’s the twist: each enemy you conquer leaves behind precious tiles. Scavenge them quickly and use strategy and speed to rebuild the arena, crafting your own fighting space even as the world falls apart.

Dynamic, colorful pixel art crafted by Laura Nadal brings each crumbling tile and fierce firefight to vibrant life, while the kinetic soundscape designed by Nicolas Ceriani magnifies every dash, shot, and triumphant rebuild. Whether you’re playing on your computer or on mobile, 6K delivers seamless controls and relentlessly fun gameplay that ramps up the adrenaline, making it impossible to play just once.

With easy-to-pick-up controls – move with WASD, shoot with your mouse, dash like lightning, and instantly build beneath your feet – every round is fast, fresh, and absolutely packed with player-driven tactics. 6K's addictive loop pushes you to outlast the collapse, plot clever rebuilds, and embrace both action and creativity. Your arena, your grit – will you survive as the ground vanishes below? Prove it. Jump in and play 6K free online now for a breakneck action fix!

How to Play

Launch 6K in your browser or mobile device and get instantly plunged into a crumbling, pixel-perfect arena. Your objective: survive as long as possible while blasting enemies and preventing the arena from disappearing beneath you!

Controls are intuitive and tailored for fluid play:

- Move using WASD (or ZQSD for alternate layouts) to weave around falling tiles and hunt for enemies.

- Dash with Shift to quickly traverse gaps or escape tight spots.

- Aim and shoot with Mouse1, targeting foes before they can outmaneuver you.

- When the ground collapses, scavenge the dropped tiles from fallen enemies and use Mouse2 to rebuild the arena—laying new pathways or safe zones beneath your feet.

- R to reload and keep your firepower primed.

Beginner tips: Always keep an eye on the ground integrity – don’t get cornered! Move quickly and smartly, firing at enemies but also prioritizing tile collection. Stay mobile and use your dash generously to avoid sudden falls. Place tiles tactically—not just for survival, but for outflanking enemies and creating strategic strongholds. With each round, you'll master the thrilling balance of destruction and creation that sets 6K apart!
